Histone H2A (1-20)-GGK(Biotin)
The Histone H2A residues 1 to 20 are derived from histone 2A (H2A) which is one of the four core histones (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.Biotin has been added to the lysine on GGK.Molecular weight:898.5 g/molHIV - 1 MN ENV - 143

Formula:C46H64N14O14Molecular weight:1,037.11 g/molHistone H3 (1-20) K4Me3, K9Ac-GG-[Lys(5-FAM)]
Histone H3 (1-20) K4Me3, K9Ac-GG-[Lys(5-FAM)] is derived from Histone 3 (H3) which is one of the four core histones fundamental for compacting eukaryotic DNA into the nucleosome.-Lysine 4 of Histone H3 (1-20) K4Me3, K9Ac-GG-[Lys(5-FAM)] has been tri-methylated, lysine 9 has been acetylated and the C-terminal has been labelled with 5-Carboxyfluorescein (5-FAM), a widely used green, fluorescent tag. Additionally, this peptide contains an uncharged C-terminal amide.LD: Histone H3 (1-20) K4Me3, K9Ac-GG-[Lys(5-FAM)] is derived from Histone 3 (H3) which is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into 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. Both H4 and H3 are highly conserved and perform roles in binding to segments of DNA which enter and leave the nucleosome and in chromatin formation. Similar to the other core histone, H3 has a globular domain and a flexible N-terminal domain, 'histone tail' which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination. 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 the positioning of the nucleosome, allowing the DNA it to be either available or inaccessible to the transcription machinery.The lysine at position 4 of this peptide has been tri-methylated and it is implicated in studies that this modification may remodel the chromatin so that it is more accessible to transcription factors, which may ultimately increase the level of gene expression. The lysine at position 9 has been acetylated, which neutralizes the positive charge on the amino acid, loosening the chromatin structure. This alteration to the accessibility of chromatin promotes the initiation of transcription.Additionally, Histone H3 (1-20) K4Me3, K9Ac-GG-[Lys(5-FAM)] has a C-terminal GKK linker labelled with 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag. This peptide also has an uncharged C-terminal amide.Molecular weight:2,866.5 g/molHXB2 gag NO-13

It inhibits the fibrillogenesis of amyloid beta protein, preventing it from aggregating into plaques.Formula:C39H59N7O6Purity:Min. 95%Molecular weight:721.95 g/molApidaecin IB
Apidaecin IB was isolated from the honeybee Apis mellifera. As a cationic proline-rich antimicrobial peptide (PrAMP), Apidaecin IB shows sequence homology with drosocin but is devoid of any pore-forming activity. Apidaecin IB is most active against gram-negative bacteria, it can navigate the outer membrane to the periplasm and then to the cytoplasm. Apidaecin IB is a non-lytic AMP, the main target of its antimicrobial activity appears to be inhibition of the chaperone heat shock protein DnaK. Toxicity appears to be exclusively to bacteria and thus has been trialled as a treatment for systemic bacterial infections. Numerous analogues and derivatives are being investigated to establish Apidaecin IB mode of action and also to improve its functionality.Formula:C95H150N32O23Color and Shape:PowderMolecular weight:2,107.42 g/molTentaGel® R RAM Resin (90 um), Rink-type

Formula:C58H94N16O14Molecular weight:1,239.47 g/molVisperas2pY
An immunoreceptor tyrosine-based activation motif (ITAM) is a phosphorylation site consisting of a conserved sequence of four amino acids that is repeated twice in the cytoplasmic tails of cell-surface non-catalytic tyrosine-phosphorylated receptors. The major role of ITAMs is its involvement in the initiation of signalling pathway and the subsequent activation of immune cells. The motif has the following structure: YxxL/I. where xx are any two amino acids. Two of these signatures are typically separated by between 6 and 8 amino acids in the cytoplasmic tail of the molecule (YxxL/Ix(6-8)YxxL/I). ITAMs are found in the CD3 and θ¶-chains of the T cell receptor (TCR) complex. TCR is a multi-subunit receptor on the surface of T cells. TCR contains two ligand binding chains containing 20 phosphorylation sites, distributed on 10 ITAMs. The TCR θ¶-chain is a homodimer subunit that contains six ITAMs (12 sites). These sites are phosphorylated by the membrane-anchored Src family tyrosine kinase Lck and Fyn and are dephosphorylated by the transmembrane phosphatases CD148 and CD45. When both tyrosines in an ITAM are phosphorylated they generate docking sites for the tandem SH2 domains of the cytosolic tyrosine kinase ZAP-70. Bound ZAP-70 can phosphorylate tyrosines on other substrates that initiate the signal transduction that leads to T cell activation. The multiple ITAMs on the TCR function mainly to amplify subsequent signalling.T cells rely on the TCR to recognize antigens, in the form of peptides bound to major histocompatibility complexes (MHC), on the surfaces of antigen-presenting cells. Binding of TCR to antigen-MCH complexes leads to proliferation, differentiation, and the secretion of effector cytokines, contributing to the elimination of infections.Molecular weight:2,672.1 g/molH-LLIYGAFSR^-OH

Apelin-36 Human
CAS:Apelin-36 (human) is derived from the apelin peptide which acts as a ligand for the apelin receptor (APJ) G protein coupled receptor and is a substrate for angiotensin converting enzyme 2. Preprapelin, encoded for by APLN located on Xq25-26.1, is cleaved to form either apelin 36, apelin 17, apelin 13, or apelin 12. As a member of the adipokine hormone family, which are involved in processes such as vascular homeostasis and angiogenesis, apelin is secreted from adipose tissue.Both apelin and the apelin receptor are widely distributed around the body thus apelin has been found to be associated with cardiovascular diseases, obesity, diabetes and cancer. Studies exploring myocardial infarction showed there to be greater apelin mRNA expression during human heart failure compared to in healthy tissue. Apelin protects against heart failure due to, the pyroglutamyl form of apelin, playing a role in decreasing infarct size of myocardial infarctions. Furthermore in rats with hypertension, the expression of apelin and APJ was decreased.Molecular weight:4,193.3 g/molH-LYL^VCGERGF-OH

Custom research peptide; min purity 95%. For different specs please use the Peptide Quote ToolTNF-alpha (1-26), human
Peptide derived from tumour necrosis factor alpha (TNF-α), a cytokine produced by macrophages, T lymphocytes and natural killer cells. It exerts its function through targeting the transmembrane receptors TNF receptor 1 and TNF receptor 2, the latter of which it has a higher affinity for. When binding to TNF receptor 1 TNF-alpha is pro-apoptotic and when binding to TNF receptor 2 it is anti-apoptotic. TNF-α has further roles in inflammation, immunity and cancer.Expression of the TNF-α gene, located on chromosome 6 in humans is regulated by factors such as nuclear factor kappa b (NFKB).Dysregulation of TNF-α and its receptors can contribute to diseases such as rheumatoid arthritis, Crohn disease and diabetes. Anti-TNF-α can be used as a therapeutic agent to target TNF-α during inflammatory diseases.Molecular weight:2,729.4 g/mol[5-FAM]-SRC Substrate Peptide
Substrate peptide for Scr, tyrosine kinase, for use in in vitro assays for Src activity.Src is a member of the Src Family tyrosine Kinases (SFKs), a large cytosolic, non-receptor, kinase family that controls multiple signalling pathways in animal cells. Src is a tyrosine kinase proto-oncogene and elevated levels of Src protein are seen in different tumours including: breast- lung- thyroid- glioblastoma- colorectal- pancreatic- prostate- gastric- biliary tract and skin cancer. Src levels are often associated with tumour progression, metastasis, and a poor clinical outcome and therefore Src has been investigated as a therapeutic target.Peptide is labelled with an N-terminal 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag.
Molecular weight:2,027.94 g/molBiotin TAT (48-60)
Biotin TAT (48-60) is a cell penetrating cationic peptide derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). The 48-60 region of the TAT peptide is an arginine-rich bascic domain which as a whole has three domains that function to aid HIV through transactivation, DNA binding and nuclear transport. As a cell penetrating peptide (CPP) TAT aids in the cellular uptake of molecules and hence serves a valuable purpose in transduction methods. This property has been demonstrated through its ability of allowing toxins such as the neurotoxin Botulinum neurotoxin Type A, produced by the Clostridium botulinum type A bacteria to penetrate the skin barrier non-invasively.This peptide has a covalently bonded N-terminal Biotin tag that can be used for detection and purification and contains an N-terminal aminohexanoic acid spacer (Ahx).Molecular weight:2,057.2 g/molH-FSIEGNR^-OH

VIP (guinea pig)
Vasoactive intestinal peptide (VIP) is a neuropeptide found throughout the body and the central nervous system. VIP is located within cell bodies and nerve endings of the enteric nervous system, brain and pancreas. VIP neurons in the peripheral system fire to regulate blood vessels, and the CNS innervate cerebral vasculature. VIP binds to G protein-coupled receptors VPAC1 and VPAC2. VIP and VPAC2 are detected in circular smooth muscle cells of cerebral arterioles. VIP and VPAC1 are also found in lymphatic tissue. VIP can block inflammation, modify the Th response favouring Th2 and induce regulatory T cells. Overexpression of each receptor has been linked to various cancers.VIP administration leads to pancreatic bicarbonate-rich fluid secretion but not to the same degree stimulated by secretin. VIP stimulates insulin secretion in a glucose-dependent manner and also stimulates glucagon secretion. Studies have found that in morbidly obese patients, VIP levels are lowered and work to slow gastric and duodenal motility but increase gastric emptying. Therefore, decreasing VIP levels in obese patients may increase weight gain by accelerating gastric emptying.VIP has been well studied in pancreatic acini. VIP is a full agonist of amylase secretion and increases cyclic AMP synchronised with an increase in intracellular Ca2+ triggered by stimuli that act through cholecystokinin (CCK) or cholinergic agonists. Most cAMP increases and amylase secretion appears to be mediated via VPAC1.

SARS-CoV-2 Spike (1196-1205)
The SARS-CoV-2 spike protein is present on the outside of the virus particles and can bind to angiotensin-converting enzyme II (ACE2) present on the host cells. The C-terminal receptor binding domain (RBD) of the spike protein binds to the N-terminal peptidase M2 domain of ACE2. This receptor binding results in the internalisation of the virus-receptor complex and is, therefore the mechanism of entry of SARS-CoV-2 into host cells.The spike protein residues SLIDLQELGK (1196-1205) from SARS-CoV-2 have been identified as a T-cell epitope with a predicted HLA restriction. Immune targeting of confirmed epitopes may potentially offer protection against SARS-CoV-2 and help the development of vaccines for long-lasting immunity.Molecular weight:1,114.6 g/molHIV - 1 MN ENV - 205

Molecular weight:1,515.7 g/mol[Cys]-Influenza Virus Nucleoprotein (311 - 325)
The Influenza Virus Nucleoprotein (311 - 325) is a component of the viral ribonucleotide complex, derived from the influenza virus and it is involved in viral replication, RNA packing and nuclear trafficking. As a monomer it contains basic residues which allow it to bind to single stranded RNA and through its flexible tail loop it has the ability to form NP oligomers.Furthermore NP is able to support the viral polymerase structurally, through associating with the two subunits PB1 and PB2, and it allows the viral ribonucleotide complex to be transported in and out of the nucleus due to its nuclear localisation and nuclear export signals.During influenza viral replication messenger RNA, viral genome RNA and complementary positive-sense RNA are produced and NP is crucial for this replication.Inhibitors of NP have potential to be used to prevent the influenza virus in humans.

[5-TAMRA]-LPETGG N-terminal Sortagging
This peptide is recognised and cleaved by the enzyme Sortase A (SrtA) from-Staphylococcus aureus. The catalytic cysteine residue in the active site of SrtA serves as a nucleophile to cleave the peptide bond between threonine and glycine. Cleavage results in the formation of a thioacyl intermediate between the peptide and SrtA. This intermediate is then resolved by the N-terminus of an (oligo)glycine nucleophile, resulting in the creation of a new peptide bond that links the peptide and its fluorescent dye to the incoming nucleophile. This method of protein labelling is known as sortagging.5-Carboxytetramethylrhodamine (5-TAMRA) is a widely used fluorescent dye which excites at 546 nm and emits at 579 nm.Color and Shape:PowderMolecular weight:983.4 g/mol(Des-Glu²²)-Amyloid β-Protein (1-42)

Annexin A1(1-25)(dephosphorylated)(human)ammonium salt
CAS:Annexin A1 is a phospholipid-binding protein that is involved in the regulation of inflammation. It is often found in atherosclerotic lesions and has been shown to be an anti-inflammatory cytokine. Annexin A1 (dephosphorylated) does not inhibit the activity of enzymes such as cyclooxygenase and lipoxygenase, and so it may have therapeutic potential for treatment of autoimmune diseases such as Crohn's disease or bowel disease. Annexin A1 also has anti-inflammatory properties, which may be due to its ability to inhibit the production of proinflammatory cytokines such as IL-6 and TNF-α by inhibiting the activation of NFκB.Formula:C141H210N32O44S·NH4Purity:Min. 97 Area-%Color and Shape:White PowderMolecular weight:3,107.47 g/molγ ABU-GSDALDDFDLDML-OH

Formula:C53H92N12O12Molecular weight:1,089.4 g/molSARS-CoV-2 Spike (999-1007)
The SARS-CoV-2 spike protein is present on the outside of the virus particles and can bind to angiotensin-converting enzyme II (ACE2) present on the host cells. The C-terminal receptor binding domain (RBD) of the spike protein binds to the N-terminal peptidase M2 domain of ACE2. This receptor binding results in the internalisation of the virus-receptor complex and is, therefore the mechanism of entry of SARS-CoV-2 into host cells.The spike protein residues GRLQSLQTY (999-1007) from C have been identified as a T-cell epitope with a predicted HLA restriction. Immune targeting of confirmed epitopes may potentially offer protection against SARS-CoV-2 and help the development of vaccines for long-lasting immunity.Molecular weight:1,064.6 g/molH-ISSPTETER^-OH

Integral membrane protein TGN38 cycles via endosomes between the cell surface and the trans-Golgi network (TGN). Peptides conjugated to the TGN38 sequence inhibit vesicle budding from TGN membranes-in vitro.-This leads to the conclusion that TGN38 is crucial for forming constitutive exocytic vesicles. The trafficking motif SDYQRL in the cytoplasmic domain at the C-terminal contains a critical tyrosine residue (Y). The motif interacts with the medium-chain adaptor subunits of AP-1/2 to allow sorting from the TGN. Mutation of the key tyrosine dramatically reduces binding affinity to AP-1/2. The flanking sequences to the trafficking motif affect the TGN38 localisation of hybrid proteins. Working with the mouse allele TGN38a has helped understand the conservation between mammalian, rat, and mouse TGN protein sequence and function. The TGN38a trafficking motif with flanking regions is provided here in an acid form with N-terminal acetylation.Molecular weight:1,489.8 g/molProinsulin 90-104
The development of type I diabetes occurs when auto-aggressive T cells are not controlled by T regulatory cells and are allowed to destroy pancreatic islet cells. This ultimately eliminates the production of insulin within the body. A more precise understanding of the regulatory T cell's antigen specificity by using antigens can provide significant clinical insights into the development of long-term diabetes. The proinsulin 90-104 fragment was used to test antigen-specific T-cell responses in type I diabetes CD4+ T cells. This peptide has helped show that the development of diabetes is linked to an increase in proinsulin-specific T regulatory cells, which may be regulating the rise in auto-aggressive T cells. Further work with the proinsulin 90-104 peptide could help design novel antigen-specific therapy.

Suc-LLVY-[Rh110]-[D-Pro]
Fluorogenic substrate peptide of the 20S proteasome. In its intact state this peptide is non-fluorescent, however when Rhodamine fluorophore is released upon hydrolysation, fluorescence can be detected. This peptide is therefore a useful tool for analysing the activity of the 20S proteasome as well as other chymotrypsin-like proteases and calpains. This peptide is also a substrate for chymase, papain, carboxypeptidase Y, proteinase yscE (kexin) and ingensin.The presence of the D-proline residue on the C terminal of the rhodamine molecule ensures one directional rhodamine cleavage which simplifies fluorescence studies. Rhodamine 110 is a laser grade fluorescent dye with excitation maxima at 496 nm and emission maxima at 522 nm.Molecular weight:1,015.5 g/molFmoc-Val-Val-OH
