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.
Masse moléculaire :2,027.94 g/molSARS-CoV-2 Spike (1192-1200)
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 NLNESLIDL (1192-1200) 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.Masse moléculaire :1,029.5 g/molH-YNEDDTFTVK^-OH

Galanin (1-30) (human) is an endogenous neuropeptide with endocrine, metabolic and behavioural effects. Galanin has a role in intestinal smooth muscle contraction, insulin and somatostatin release, and synaptic neurotransmission.Galanin is widely distributed in the central nervous, peripheral, and endocrine systems. 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 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 Galphai/o pathway. Activation of the receptor leads to a cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.Galanin protects against various physiological insults in vitro, including excitotoxicity and β-amyloid toxicity. Changes in galanin have been widely studied concerning Alzheimer's disease, and galaninergic neurons are spared in late-stage Alzheimer's relative to non-galaninergic neurones.Galanin (1-30) has been used as an agonist for the GalR2 receptor in vitro for calcium mobilisation assays to understand the role Galanin/GalR2 play in multiple sclerosis.Galanin (1-30) is provided with an N-terminal 5-FAM, a widely used green fluorescent reagent ideal for peptide labelling and detection. The excitation/emission for this reagent is 490 nm/520 nm.Masse moléculaire :3,513.6 g/molAnnexin A1 (2-12)
Annexin A1 (2-12) is derived from the Annexin A1 protein which is a member of the Ca2+ dependent phospholipid binding protein family of Annexins A1 to A13. Structurally Annexin is comprised of a C-terminal core region and an N-terminal region. Calcium binding sites featured in the core region allow Annexin A1 to bind to cell membranes to induce membrane aggregation in a calcium dependent manner. Furthermore Annexin A1's N-terminal region performs extracellular signalling through forming complexes with SH2 domain containing proteins. Different lengths of the Annexin family's N-terminus contributes to how the Annexins effect key processes such as cell proliferation, apoptosis, growth and differentiation.Annexin A1 can be categorised as being both anti-inflammatory and pro-inflammatory. One example of how Annexin A1 demonstrates anti-inflammatory properties is through activating the formyl peptide receptor family's (FGRs) downstream cascade. Consequently the extracellular regulated kinase (ERK) and mitogen-activated protein kinase (MAPK) are phosphorylated, causing subsequent transcription factors involved in the regulation of T cells to generate anti-inflammatory effects. Another is through inhibiting phospholipase A2 which prevents the release of inflammatory factors and the formation of arachidonic acid precursors. This property has contributed to inflammation studies such as where the inhibition of pro-inflammatory prostaglandins by Annexin A1 was used to investigate leukocyte aggregation.During its anti-inflammatory role Annexin A1 uses the active peptide Ac2-26 located on its N-terminus. It is evident Annexin A1 can be labelled as being pro-inflammatory due to it inducing pro-inflammatory cytokines, following its phosphorylation by PKC. This results in its translocation into the nucleus of BV-2 microglial cells.Couleur et forme :PowderMasse moléculaire :1,351.59 g/molH-YMLDLQP^ET-OH

The SARS-CoV-2 non-structural protein 13 (NSP13) has been identified as a target for anti-viral therapeutics due to its highly conserved sequence and is essential for viral replication. NSP13 is part of the helicase superfamily 1B. As an NTPase and RNA helicase, NSP13 binds to RNA-dependent RNA polymerase and acts in concert with the replication-transcription complex to stimulate backtracking and further activate NSP13 helicase activity. These factors make NSP13 a good target for developing new antiviral drugs. In addition, the identification of epitopes within the NSP13 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. NSP13 (321-335) 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 :1,729 g/molbeta-Amyloid (1-10) Biotin
β-Amyloid 1-10 (Aβ1-10) is one of many short Aβ species found in vivo and is formed by the cleavage of amyloid β precursor protein by β- and α-secretase.-Amyloid β-protein (Aβ) has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer disease (AD) and Down 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 α-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. Biotin is C-terminally linked to the peptide via ethylenediamine-for convenient detection and purification. Alternative β-Amyloid fragments and labels are also available, please refer to our peptide catalogue for availability.

Masse moléculaire :1,367.7 g/molTAT (48-60) amide
TAT (48-60) amide 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 an uncharged C-terminal amide.
