Histone H2A (1-20)
The histone H2A residues 1-20 are derived from histone 2A (H2A) which is one of the four core his-tones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into a structure known as the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core.At the site of DNA entry on the outer nucleosome, the C-terminus of H2A is present and is able to interact with linker histones or other factors. This allows for variation and changes in nucleosome stability to occur. Furthermore Histone H2A has histone variants such as H2A.Z and H2A.X (which are present in all organisms) and these variants alter the organisation of the DNA.Due to histones containing a large number of lysine and arginine residues they have a positive net charge which interacts in an electrostatic manner with the negatively charged phosphate groups in DNA. The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter to change the positioning of the nucleosome, allowing the DNA it to be either available to the transcription machinery or inaccessible.Peso molecolare:2,086.2 g/mol5Fam-DPASNLGLEDIIRKALMGSFDDK-OH

[5-FAM]-beta-Amyloid (1-15) Human
Fluorescein labelled amyloid β 1-15 (Aβ1-15 ). Aβ1-15 is one of many short Aβ species found in vivo and is formed by the cleavage of Aβ precursor protein by β- and alpha-secretase.Amyloid β-protein (Aβ) has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer's disease (AD) and Down's syndrome (DS). Aβ has therefore been extensively studied as a potential target for treatment of AD.Aβ is formed from the cleavage of the large, transmembrane protein- APP (amyloid precursor protein). Cleavage of APP by β- and then γ-secretases results in the formation of Aβ. Aβ can aggregate to produce amyloid-β oligomers, which are thought to be highly neurotoxic. Over time Aβ can further aggregate to produce the characteristic senile plaques present in AD and DS. Aβ can be degraded by enzymes such as neprilysin, insulin degrading enzyme or endothelin converting enzyme. At physiological levels Aβ may be involved in controlling synaptic activity and neuronal survival.Fluorescein (FAM) is a hugely popular fluorescent tag due to its excellent fluorescence quantum yield and relatively high absorptivity as well as being highly water soluble.Peso molecolare:2,183.8 g/molHXB2 gag NO-52

AD01 is a derivative of the FK506 binding protein-like (FKBPL), and exerts potent anti-angiogenic activity in vitro and in vivo to control tumour growth. Recent studies have shown that AD-01 inhibits Rac-1 activity, and up-regulates RhoA and the actin binding proteins, profilin and vinculin. In this way, the anti-angiogenic proteins, FKBPL, and AD-01, offer a promising and alternative approach for targeting both CD44 positive tumours and vasculature networks. Recent clinical studies have shown that AD01 and other FKBPL-based peptides may offer an alternative for targeting treatment-resistant breast cancer stem cells.Peso molecolare:2,574.3 g/molHLA-A*02:01 Polymerase (417-425)
HLA-A*02 is a class I major histocompatibility complex (MHC) allele which is part of the HLA-A group of human major histocompatibility complex (MHC) leukocyte antigens (HLA). HLA-A is a human MHC class I cell surface receptor and is involved in presenting short polypeptides to the immune system. These polypeptides are typically 7-11 amino acids in length and originate from proteins being expressed by the cell. Cytotoxic T cells in the blood "read" the peptide presented by the complex and should only bind to non-self peptides. If binding occurs, a series of events is initiated culminating in cell death via apoptosis. Hepatitis B virus (HBV) polymerase is a multifunctional enzyme that can use both RNA and DNA as a template for amplification and also has an RNase H function. First the polymerase acts on the HBV pre-genomic RNA (pgRNA) to reverse transcribe it to form the (-) DNA strand. Simultaneously the RNA template is degraded by the polymerases RNase H activity, except for a stretch of RNA at 5' end of the pgRNA which is used to prime the synthesis of the (+) DNA strand. This process results in a new partially double-stranded relaxed circular DNA molecule (rcDNA) within a new capsid.

YSA binds to the extracellular domain of ephrin type-A receptor 2 (EphA2) with high affinity and selectivity. YSA binding activates EphA2 and its tumour suppressing downstream signalling pathways (including inhibition of the PI3K/Akt and ERK pathways), and promotes receptor internalisation.EphA2 is highly expressed in many types of solid tumour, and the level of EphA2 expression is positively correlated with malignancy and poor prognosis in some cancer types.YSA has been shown to be an effective targeting peptide of chemotherapeutic drugs to EphA2 expressing tumours. YSA-drug conjugates are able to selectively target EphA2 expressing tumours, both activating tumour supressing downstream signalling pathways, and becoming effectively internalised by cancer cells to further increase the potency of the chemotherapeutic drug. YSA-drug conjugates have been shown to be dramatically more effective at inhibiting tumour growth than chemotherapy alone. Selective tumour targeting with YSA could also reduce the systemic toxicity caused by nonselective and highly toxic chemotherapy agents, and thus reduce adverse side effects of chemotherapy.The uncharged C-terminal amide has the potential to increase the biological activity of this peptide.Peso molecolare:1,345.6 g/molPTH (1-34) human
PTH 1-34, is a biologically active peptide fragment of parathyroid hormone (PTH). PHT 1-34 has been shown to enhance bone fracture healing by promoting osteogenesis. PTH 1-34 also has chondrogenic properties.PTH is an 84-amino-acid polypeptide hormone (PTH 1-84) which is secreted by the parathyroid glands along with its fragments (such as PTH 1-34 and PTH 7-84). PTH increases calcium and decrease phosphate levels in the blood and the abundance of PTH-derived peptides is regulated by blood calcium levels. PTH inhibits the bone growth-promoting activity of osteoblasts and induces osteoclasts to resorb bone and release calcium and phosphate ions into the blood. PTH binds to and activates the receptor parathyroid hormone receptor 1 (PTHR1). PTHR1 is a G-protein-coupled receptor (GPCR) which regulates mineral ion homeostasis, bone turnover and skeletal development.Colore e forma:PowderPeso molecolare:4,115.1 g/molGalanin Human
Galanin is a neuropeptide synthesised and released by the brainstem locus coeruleus (LC). Galanin is expressed in most LC neurons in rodents and humans. Galanin has been shown to inhibit LC activity by hyperpolarising LC neurons, suppressing their spontaneous firing rate, and enhancing alpha2-adrenergic receptor-mediated negative feedback. Galanin is also a potent trophic and neuroprotective factor throughout the nervous system.Galanin is widely distributed from the central nervous system, peripheral regions and endocrine system. Galanin's overarching function is as an inhibitory, hyper-polarizing neuromodulator for classical neurotransmitters like acetylcholine and serotonin. Galanin interacts with 3 receptor subtypes GalR1-3 which are G protein-coupled receptors and are inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway but unlike GalR1 there is detectable inositol phosphate production. GalR3 is associated with the Gα pathway, activation of the receptor leads to cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.Galanin protects against a variety of physiological insults in vitro, including excitotoxicity and β-amyloid toxicity. Changes in galanin have been widely studied in relation to Alzheimer's disease and galaninergic neurons have been shown to be spared in late-stage Alzheimer's relative to non-galaninergic neurones.Peso molecolare:3,157.41 g/mol(PFR)2-[Rh110]
Soybean trypsin inhibitor inhibits trypsin, factor Xa, plasmin, and plasma kallikrein activity in serum-free cell culture media. It does not inhibit metallo-, cysteine, aspartic proteases, or tissue kallikrein (serine proteases).Kallikreins (KLKs) are a large family of secreted serine proteases with either trypsin-like or chymotrypsin-like specificity which carry out many biological functions. The KLK proteases are involved in pathways that regulate skin desquamation, tooth enamel formation, kidney function, seminal liquefaction, synaptic neural plasticity, and brain function. Disruptions in the function of KLK activity has been linked to several pathologies, including respiratory diseases, neurodegeneration, anxiety, schizophrenia, skin-barrier dysfunction, pathological inflammation, and cancer.Peso molecolare:1,130.6 g/molH-KFRKAFKR^FF-OH

Relaxin-3 is part of the insulin/relaxin superfamily with various roles, including appetite, stress, and addiction. Relaxin-3 binds to its cognate receptor relaxin family peptide 3 receptor (RXFP3). B1-22R is a single-chain relaxin-3 antagonist for RXFP3 no interaction is found with RXFP1 or RXFP4. B1-22R is a truncation of the B-chain of relaxin-3 and the addition of an arginine residue at the C-terminus-B1-22R acts as a RXFP3 antagonist. B1-22R has been used to perform structural analysis relationships (SARs) and residue scanning to understand the critical residues and conformation of the interaction between B1-22R and RXFP3. B1-22R can generate more potent analogs of relaxin-3 that are more stable and serve as models for drug design targeting the relaxin-3 receptor for regulation of addiction, stress, and appetite.B1-22R is provided in the amide form.Peso molecolare:2,620.5 g/molH-LVVVGAGGVGK^-OH

CBL (167-180) is derived from the CBL E3 ubiquitin ligase which targets receptor tyrosine kinases to lysosome degradation. CBL and its family member CBL-B are expressed in hematopoietic cells and as E3 ubiquitin ligases they contain a tyrosine kinase domain and an RF domain joined by a linker domain. The function of the RF domain is to transfer ubiquitin from E2 ubiquitin-conjugating enzymes onto the target protein which is often phosphorylated. Consequently the ubiquitinated substrate, the receptor tyrosine kinases, are ultimately targeted to the lysosome for degradation.EGFR is an example of a receptor tyrosine kinase whose activation is prevented by CBL and CBL-B when they bind and recruit GRb2, the adapter protein to EGFR. Consequently the ubiquitinylation of EGFR occurs and targets it for recognition by the endosomal protein complex and then lysosome degradation.It has also been found that the CBL family can negatively regulate through ubiquitinylation, PI 3-kinases, Rap G-protein guanine nucleotide exchange factor (GEF), C3G and Rho GTPase GEF Vav which are all non-receptors.If CBL becomes non-functional it can be associated with malignancies such as acute myeloid leukemia and myelodysplastic syndrome.

Identification of cell penetrating conjugates has aided numerous areas of scientific development. The Drosophila transcription factor Antennapedia contains a homeodomain that can be internalised by cells to the cytoplasm and to the nucleus in a receptor-independent mechanism. The key residues for internalisation have been sequenced (RQIKIWFQNRRMKWKK), named penetratin, and used in several studies to aid entry of fusion proteins into cells.The full 60 amino acid homeodomain was fused to a T cell epitope of the influenza nucleoprotein and successfully internalised into T cells for presentation. The CPP, penetratin, was fused to a ligand for Grb-2 resulting in inhibition of downstream Grb-2 signalling events.- Penetratin has also been used in vivo to prime cytotoxic T lymphocytes by conjugating short antigenic peptides to the CPP. Penetratin is provided here as a C-terminal acid but is also available in amide form.Peso molecolare:2,246.73 g/molBombesin
Bombesin was originally isolated from the skin of the european fire-bellied toad (Bombina bombina) and has two known homologues Neuromedin B (NMB) and gastrin-releasing peptide (GRP).Bombesin-like peptides are involved in many physiological functions including: regulation of food intake- anxiety and fear-related behaviour, thermoregulation, stress response, learning and memory and in the stimulation of smooth muscle contraction. Bombesin is also a tumour marker for small cell carcinoma in the lung, gastric cancer, pancreatic cancer, and neuroblastoma.The receptors for these two peptides are known as bombesin receptor type 1 (BB1 also known as NMB receptor) and bombesin receptor type 2 (BB2 also known as GRP receptor). Bombesin shows high affinity to both of these receptor subtypes. These bombesin-like peptides and their receptors are widely distributed in the central nervous system (CNS) and gastrointestinal (GI) tract.This peptide contains an N-terminal pyroglutamyl to prevent the intramolecular cyclisation of the N-terminal of glutamine to N-pyroglutamate (pGlu).Peso molecolare:1,618.8 g/molEC dipeptide

Flagellin is a structural protein which forms the major portion of bacterial flagellar filaments. The N- and C-terminals of flagellin are highly conserved regions, whereas the central core can vary greatly between bacterial species. Flagellin 22 (flg22) is the stretch of amino acids most conserved across bacterial species and is located towards the N-terminal of the flagellin protein.Flg22 is a potent elicitor of plant immune responses and is recognised in plants by the membrane bound leucine-rich repeat-receptor kinase FLAGELLIN SENSITIVE 2 (FLS2). Flg22 induces defence gene expression to trigger both local and systemic immune responses and is thus widely used in plant defence studies.Colore e forma:PowderPeso molecolare:2,272.48 g/molH-FPAIQNLALR^-OH

CREB327/active transcription factor CREB-A (113-126) [5-FAM] amide, Human
CREB is a transcription factor that regulates diverse cellular responses including: proliferation- survival and differentiation- adaptive immune responses- glucose homeostasis- spermatogenesis- circadian rhythms and synaptic plasticity associated with memory. CREB is induced by a variety of growth factors and inflammatory signals and subsequently mediates the transcription of genes containing a cAMP-responsive element, including IL-2, IL-6, IL-10, and TNF-alpha. In the immune system, CREB induces an anti-apoptotic survival signal in monocytes and macrophages, has a role in promoting the proliferation, survival and regulation of T and B lymphocytes and is required for the generation and maintenance of regulatory T cells. CREB also often promotes anti-inflammatory immune responses, such as through the inhibition of NF-KB activity, the induction of IL-10, and the generation of Tregs. These anti-inflammatory responses could be protective by inhibiting unwanted inflammation, tissue damage, and autoimmune responses, or they could be pathogenic in the context of infection and tumour immunosurveillance. Peptide is labelled with an N-terminal 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag.Peso molecolare:2,087.1 g/molDystrophin (2690-2700)
Forms of inherited muscular dystrophy such as Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) result from mutations targeting the dystrophin gene. These disorders are X-linked, progressive, and cause the gradual weakening of the muscles leading to respiratory failure and ultimately reduces the patient lifespan.In DMD, mutations lead to the production of premature stop codons and hence the truncated dystrophin protein product is vulnerable to nonsense mediated decay and degradation. Therefore, dystrophin production in muscle cells is reduced. On the other hand, nonsense mutations which also contribute to DMD, cause exon skipping in BMD and result in an internally truncated protein product which are partially functional. The symptoms of BMD are later onset compared with DMD which develop in patients between 2 to 7 years.Treatments of dystrophin disorders are in clinical trial including antisense oligonucleotide exon skipping and gene therapy. However, the efficacies of these treatments are not easily quantified. Currently levels of muscular dystrophin are quantified by western blot which can be unreliable. The peptide provided here, aligning residues dystrophin (2690-2700), has been tested via western blot, mass spectrometry, immunostaining and RT-PCR to try and provide the most robust method of validation of dystrophin levels possible. Further study with this dystrophin fragment could prove to be a vital step in the understanding and treatment of dystrophin disorders. Within our catalogue we also have other peptides tested for dystrophin quantification available plus the full-length dystrophin protein.MOG (34-56) Human amide
Myelin oligodendrocyte glycoprotein (MOG) is a member of the immunoglobulin (Ig) protein superfamily and is expressed exclusively in the central nervous system (CNS) on the surface of myelin sheaths and oligodendrocyte processes. MOG is expressed at the onset of myelination, and therefore is a potential marker for oligodendrocyte maturation.MOG contains an extracellular domain, a transmembrane domain, a cytoplasmic loop, a membrane-associated region and a cytoplasmic tail. MOG may function as a cell surface receptor or cell adhesion molecule. Fifteen different alternatively spliced isoforms have been detected in humans. These are present either on the cell surface, the endoplasmic reticulum in the endocytic system, or in secreted form.The secreted form of MOG may trigger autoimmunity if released into the cerebrospinal fluid and periphery. MOG is thought to be a key target for autoantibodies and cell-mediated immune responses in inflammatory demyelinating diseases such as multiple sclerosis (MS) and is therefore widely studied in this field.The MOG (34-56) fragment is in the most potent auto-antigenic region of MOG, and is highly effective at inducing experimental autoimmune/allergic encephalomyelitis (EAE), an animal model that resembles MS. This peptide has an uncharged C-terminal amide.Colore e forma:PowderPeso molecolare:2,763.14 g/molSIVmac239 - 20

Reactivity to human leukocyte antigens (HLAs) is a risen concern in clinical treatments such as organ transplant rejection. Understanding the epitopes causing reactivity and the signalling pathways could lead to better clinical therapies. The peptides presented by the non-classical HLA-G are important for a largely tolerogenic role and are considered part of an immune checkpoint. This, therefore, makes understanding ligand characteristics and HLA-G a target for cancer therapies. The HS1 fragment (160-168) has been identified as an epitope that human leukocyte antigen HLA-G naturally presents, determined by liquid chromatographic tandem mass spectrometry (LC-Ms/MS). This epitope has been used extensively in the literature to help understand the natural ligand presentation of HLA-G.For example, leukocyte immunoglobulin (Ig)-like receptors (LILRs) are key regulators of the immune response and therefore targets for therapeutics. Inhibitory LILRB1 and LILRB2 with HLA-G are pivotal for immunotolerance during pregnancy and autoimmune diseases plus cancer cell immune evasion. HS1 fragment (160-168) was used in binding affinity assays to clarify the conformational plasticity of the interaction between the receptor, the HLA antigen, and the various peptides HLA-G can accommodate.Colore e forma:PowderPeso molecolare:1,091.6 g/mol[5-FAM]/[Lys(Dnp)]-SARS-CoV-2 S1/S2
Fluorescence resonance energy transfer (FRET) peptide substrate derived from SARS-CoV-2 spike (S) S1/S2 site. This FRET peptide exhibits internal fluorescence quenching when intact, however hydrolysis of the peptide between the donor/acceptor pair generates fluorescence, enabling the quantitative measure of enzymatic activity. The S1/S2 site of SARS-CoV-2 S is efficiently cleaved by a wide range of proteases including furin.SARS-CoV-2 Spike (S) protein is one of the four essential structural proteins from the coronavirus SARS-CoV-2. S protein is a large, class I viral transmembrane protein essential for viral entry into the cell via binding to the host angiotensin-converting enzyme 2 (ACE2) receptor. S assembles as a trimer on the surface of the virion, giving it its distinctive 'corona' or crown-like appearance. The ectodomains of S proteins are divided into two subunits, S1 and S2. S1 helps in host receptor binding and is further divided into two subdomains: N-terminal domain (NTD) and C-terminal domain (CTD), both of which act as receptor-binding domains. The S1 CTD contains the receptor-binding motif (RBM). The S2 subunit accounts for fusion. Peptide contains an N-terminal 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag and a 2, 4-dinitrophenyl (Dnp) quencher.Peso molecolare:1,864.8 g/molCNP (1-22), Human, Porcine
C-type natriuretic peptide (CNP) is expressed from numerous tissue types but primarily within the central nervous system and the bone. CNP binds the natriuretic peptide receptor B (NPR-B) and acts as an autocrine/paracrine factor. CNP signalling acts as a positive regulator of endochondral bone growth. Both CNP and NPR-B are being explored as therapeutic targets for growth disorders including achondroplasia. CNP (1-22) is the major form of CNP found in the plasma. Exogenous CNP (1-22) can be cleared quite effectively, administration of a constant 'high' dose was able to overcome this obstacle to induce endochondral ossification and accelerated bone growth. However, CNP (1-22) may have the potential to induce systemic vascular resistance and blood pressure issues which would need to be addressed before future clinical applications. Researchers are trying to better establish the function and role of CNP (1-22) one strategy has been the addition of conjugates, such as the C-terminal of ghrelin, to try and improve the clinical efficacy.Colore e forma:PowderPeso molecolare:2,196.1 g/molovalbumin (371-382), chicken

Orexin B is one of two closely related peptides- the orexins (also known as hypocretins). These small neuropeptides are secreted from orexin-containing neurons, located mainly in the lateral hypothalamus (LH). Orexins function via the binding and activation of two G-protein-coupled receptors (GPCRs)- orexin receptor type 1 (OX1) and 2 (OX2).[Ala(11), D-Leu(15)]orexin-B is a highly potent and selectiveOX2 receptor agonist which can discriminate between the OX1 and OX2 receptors, with a 400-fold selectivity for the OX2 over OX1. [Ala(11), D-Leu(15)]orexin-B is therefore a beneficial tool for addressing the functional roles of OX2.The L-leucine residue at position 11 of orexin B is important for selectivity to OX2 over OX1. L-Alanine substitution at position 11 and D-leucine substitution at positions 15 maintain the potency of orexin-B to OX2, while significantly reducing the potency for OX1.Orexins play several vital roles in a range of physiological activities, including: circadian rhythm- feeding behaviour- energy balance- glucose metabolism- neuroendocrine functions- stress-adaptive responses and reward and addiction. Orexins have also been linked to the pathological processes of neurological diseases such as: narcolepsy- depression- ischemic stroke- drug addiction and Alzheimer's disease.Peso molecolare:898.5 g/molBiot-KKSRGDYMTMQIG-NH2

CAS:Secretin is a gastrointestinal hormone secreted by S cells in the small intestine, targeting G-protein coupled secretin receptors in numerous cell types. Secretin is synthesised from the preprohormone pro-secretin and is involved in regulating gastric acid and bicarbonate ion secretion in the duodenum and regulating water homeostasis. During glucose intake, secretin stimulates the pancreas to release insulin.Secretin has clinical relevance as a method to detect gastrin-producing tumours. Administration of exogenous secretin to the duodenum for secretin stimulation test to occur. Secretin can also be used to detect pancreatic insufficiencies via s administration during endoscopic retrograde cholangiopancreatography (ERCP). This allows the detection of inflammatory and neoplastic conditions of the pancreas.Secretin plays a different role in the central nervous system, such that in secretin deficient mice, synaptic plasticity and hippocampal synaptic activity are altered.
