Elf18
Translation elongation factor thermo unstable (EF-Tu), is a highly conserved protein in bacteria which is essential for the synthesis of new proteins through translation in the ribosome. EF-Tu is also a pathogen-associated molecular pattern (PAMP) protein. PAMPs are elicitors of plant defences and are recognised by pattern recognition receptors in the plant. In Arabidopsis thaliana EF-Tu is recognised by EF-Tu Receptor (EFR), a leucine-rich repeat-receptor kinase XII family member.Elf18 represents the N-terminal of EF-Tu, the region specifically recognised by Arabidopsis. This N-acetylated peptide is a strong inducer of plant defence responses and results in the biosynthesis of ethylene in leaves which triggers resistance to subsequent infection by pathogenic bacteria.Couleur et forme :PowderMasse moléculaire :2,068.1 g/molRKOpep
Peptide identified through phage display that binds to colorectal cancer cell line RKO cells, as well as other cancer cells including Caco-2, HCT 116 and HCT-15, but not to normal cells, possibly through targeting the monocarboxylate transporter 1, which has been implicated in colorectal cancer progression and prognosis.
Masse moléculaire :920.4 g/molLeptin (93 - 105) Human
Leptin is a member of the adipocytokines or adipokines group of cytokines primarily produced in adipose tissue. Leptin is a hormone involved in multiple endocrine functions, bone metabolism and thermoregulation, and a cytokine promoting inflammatory responses. There are elevated levels of leptin found in people with obesity. This contributes to the state of low-grade inflammation that makes those individuals more likely to develop cardiovascular diseases, type II diabetes, degenerative disease and autoimmune disease. Reduced levels of leptin, found in malnourished individuals, have been linked to an increased risk of infection and reduced cell-mediated immunity.Leptin binds to leptin receptors (ObRs), of which there are at least six isoforms (ObRa, ObRb, ObRc, ObRd, ObRe, and ObRf). Leptin-related analogs such as (93-105) fragment can mimic the interaction and activation of the ObR to improve their anti-obesity effects. Peptide vectors with a linker to a leptin fragment were patented as new leptin agonists with an improved permeability through the blood-brain barrier. Administration of leptin or leptin (93-105) to rats was shown to raise the blood levels of aldosterone and corticosterone. The use of the (93-105) fragment has allowed a better understanding of full-length leptin and its function in its various roles.Couleur et forme :PowderMasse moléculaire :1,526.8 g/molGLP-1 (7-36) [Cys(Sulfocyanine5)]
The native form of GLP-1 in humans is the GLP-1 (7-36) amide. GLP-1 (7-36) amide is highly unstable (half-life <-2 minutes) due to proteolytic degradation by the serine protease, dipeptidyl peptidase-IV (DPP-IV). DPP-IV cleaves the N-terminal histidine and alanine residues from GLP-1 to generate two equipotent forms: GLP-1 (9-37) and GLP-1 (9-36) amide. This degradation mitigates against the therapeutic use of GLP-1 itself, therefore DPP-IV-resistant peptide analogues have been developed and licensed for clinical use.Contains a sulfo-Cyanine5 fluorescent dye, an analogy of Cy5® and one of the most popular fluorophores. Sulfo-Cyanine5 is a red emitting fluorescent dye which is highly hydrophilic and water-soluble. Compatible with various equipment such as plate readers, microscopes, and imagers.Couleur et forme :PowderMasse moléculaire :4,162.9 g/molDefensin HNP-3 (human)

The coronavirus (CoV) nucleoprotein is the major component of CoV structural proteins. Also known as the nucleocapsid protein, it is an abundant RNA-binding protein critical for viral genome packaging. These factors make nucleoprotein a good target for developing new antiviral drugs. In addition, the identification of epitopes within the nucleoprotein sequence can help design more effective SARS-CoV-2 vaccines.Models have predicted epitopes exhibiting antigenicity, stability and interactions with MHC class-I and class-II molecules. Nucleoprotein (266-280) is an epitope candidate with various HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.Masse moléculaire :1,692.9 g/molH-YSDYFKPFSTGK^-OH

GIP (1-30) Human amide is derived from the Gastric inhibitory peptide (GIP). Gastric inhibitory polypeptide (GIP) is an inhibiting hormone of the secretin family of hormones. While GIP is a weak inhibitor of gastric acid secretion, its main role is to stimulate insulin secretion - in a glucose-dependent mechanism. Therefore, GIP is referred to as a glucose-dependent insulinotropic peptide.GIP is derived from a 153-amino acid pro-protein encoded by the GIP gene. It is synthesised by K cells, which are found in the mucosa of the duodenum and the jejunum of the gastrointestinal tract. GIP receptors are seven-transmembrane proteins found on β-cells in the pancreas. These β-cells are those that are able to simultaneously detect glucose and release insulin as a result to GIP binding.The clinical relevance of GIP is related to type 2 diabetes mellitus (T2DM)- studies have found that T2DM diabetics are unresponsive to GIP and have lower levels of GIP secretion after a meal when compared to non-diabetics. In research involving knockout mice, it was found that absence of the GIP receptors correlates with resistance to obesity.

Amino acids 1-6 of amyloid β peptide (Aβ). This fragment represents an immunogenic portion of Aβ which has been used as the basis for potential immunotherapies for Alzheimer's disease. 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.Contains a GGC linker, the thiol on the Cysteine can be used for conjugation to dyes and other molecules.Couleur et forme :PowderMasse moléculaire :990.4 g/molLeuprolide Acetate
Leuprolide acetate is a synthetic peptide analogue of naturally occurring gonadotropin releasing hormone (GnRH also known as luteinising hormone-releasing hormone, LHRH). Leuprolide Acetate has a longer half-life and a higher affinity to the pituitary GnRH-receptor than physiological GnRH due to the presence of a D-amino acid. Leuprolide acts as a super-agonist of the pituitary gonadotropin-releasing hormone (GnRH) receptor in the hypothalamo-pituitary-gonadal axis and disrupts the maintenance of the normal hypothalamo-pituitary-gonadal axis and desensitizes the GnRH receptor. This results in lower levels of testosterone in the blood. Leuprolide is used to treat prostate cancer, endometriosis, fibroids and precocious puberty. Peptide is for research purposes only, strictly not for human use.Masse moléculaire :1,208.6 g/molClick Tat (47-59)
Tat (47-59) 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). Specifically, TAT (47-57) is located within the arginine-rich basic domain of the TAT peptide. TAT has three domains which 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.Tat (47-59) is provided here with a N-terminal alkyne attachment. Two of the most regularly encountered functional groups for click chemistry are azides and alkynes, and the azide-alkyne cycloaddition has become the most popular click reaction. The use of click chemistry with alkyne-Tat (47-59) allows a wide variety of applications particularly for conjugation, modification, and peptide design.Couleur et forme :PowderMasse moléculaire :1,797.1 g/molCONSENSUS B Tat - 19

Heat shock proteins (Hsps) are highly conserved and stress inducible. Hsp70 has been found in tumour cell lines to be highly expressed with a higher plasma membrane localisation. This is correlated to the cell sensitivity to natural killer (NK) cell-mediated lysis. Investigation identified that Hsp70 N-terminal extended peptide TKD (450-463) was critical for this to occur. TKD (450-463) with low dose interleukin (IL-2) has the same capacity to induce NK cell proliferation and activity as the full-length protein Hsp70. Excess of Hsp70 and TKD (450-463) both inhibit cytolytic activity by NK cells. Other related sequences tested did not lead to NK cell-mediated lysis. Further study with the TKD (450-463) epitope could elucidate how NK cells are activated by Hsp70s as the mechanism remains unclear.Masse moléculaire :1,562.8 g/mol[Aurora™ Fluor 647]-RGD peptide

FRET peptide substrate for the severe acute respiratory syndrome coronavirus main protease (SARS-CoV Mpro). The substrate sequence is derived from residues P4-P5' of the SARS-CoV Mpro N-terminal autoprocessing site which has the sequence AVLQSGFRK. SARS-CoV Mpro is a key antiviral target.This peptide contains an N-terminal 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag and the Dabcyl fluorescence quencher. When the peptide is intact, fluorescence is undetectable due to the proximity of the Dabcyl quencher to the 5-FAM fluorophore. However upon cleavage of the peptide by SARS-CoV Mpro, the 5-FAM group and the Dabcyl quencher are separated and fluorescence can be detected. This therefore represents a useful tool for investigating SARS-CoV Mpro activity.Couleur et forme :PowderMasse moléculaire :1,740.8 g/molThrombin Receptor Antagonist

ANP (human) is derived from the atrial natriuretic peptide (ANP) which is a cardiac hormone involved in maintaining cardio-renal homeostasis. This occurs through the activation of the guanylyl cyclase-coupled receptor, resulting in the increased concentration of cyclic guanylate monophosphate. Moreover its function in the processes of anti-proliferation and anti-angiogenesis allow it to take part in cardiovascular remodelling.ANP is a member of the natriuretic peptide family and it is encoded by the NPPA gene, located on chromosome 1. Once synthesized from the 151 amino acid pre-prohormone into its biologically active form, ANP is secreted by the atrial cardiomyocytes in the circulating forms: ANP (1-98) and ANP (99-126). This synthesis process involves the signal peptide being removed from the pre-prohormone resulting in pro-ANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.At the N-terminus Azhx, 6-azidohexanoic acid, is present.
Masse moléculaire :3,219.5 g/molTAT-NR2B (C-ter)
N-methyl-D-aspartate receptors (NMDARs) are ligand-gated ionotropic glutamate receptors that mediate excitatory synaptic transmission and play important roles in many aspects of nervous system function including: synaptic plasticity- learning and memory- neuronal development and circuit formation. NMDARs have been implicated in various neuronal disorders. NMDARs are heteromers consisting of an obligate NR1 subunit and most commonly one or two kinds of NR2 subunits or occasionally NR3 subunits. NR2B is the predominant subunit found in the postnatal brain, however over time the number of NRA2 subunits increase and eventually outnumber NR2B subunits in a process known as the NR2B-NR2A developmental switch. The greater ratios of the NR2B subunit in post-natal brains leads to NMDA receptors which remain open longer compared to those with more NR2A subunits, this may be related to the greater memory abilities in the immediate postnatal period compared to late in life. NR2B improves synaptic plasticity and memory when over-expressed in neurones. The involvement of NMDAR in the central nervous system (CNS) has become a focus area for neurodegenerative diseases such as Alzheimer's disease, epilepsy and ischemic neuronal cell death.The TAT peptide is present due to its properties as a cell penetrating cationic peptide (CPP). It 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). As a CPP, TAT is able facilitate the delivery of NR2B (C-ter) across the plasma membrane.Couleur et forme :PowderMasse moléculaire :2,517.4 g/mol
