LL-37 is a member of the large cationic family of anti-microbial peptides called cathelicidins which have broad-spectrum anti-microbial activity and are expressed in many species. The only cathelicidin found in humans is LL-37, this is produced in epithelial cells, by proteolytic cleavage from the C-terminal of the hCAP-18 protein. LL-37 can be processed into different forms of anti-microbial peptides. As well as its anti-microbial properties LL-37 also regulates many aspects of the innate immune system and overexpression of LL-37 has been linked to autoimmune diseases such as asthma and psoriasis, making LL-37 the most studied form of the human cathelicidin peptides.More recently, studies have shown that LL-37 binds to SARS-CoV-2 S protein and inhibits binding to its receptor hACE2, which may inhibit viral entry into the cell.

Orexin A 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 (OX1R) and 2 (OX2R).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.This Orexin A peptide contains two disulphide bridges, one between cysteine 7 and cysteine 13, and the other between cysteine 8 and 15.

This peptide is phosphorylated by Janus kinase 2 and 3 (JAK2 and JAK3) and is an ideal substrate for use in kinase assays. The JAK family of kinases is essential for the signalling of a host of immune modulators in tumour, stromal, and immune cells where they are highly expressed. JAK family proteins mediate the signalling of the interferon (IFN), IL-6, and IL-2 families of cytokines.JAK kinases are associated with cytokine receptors. Cytokine binding to these receptors results in activation of JAK kinases and receptor phosphorylation. Phosphorylated cytokine receptors recruit STAT proteins, which are then phosphorylated by the activated JAK kinases. Phosphorylated STAT proteins form homo- and hetero-dimers that translocate into the nucleus and function as transcription factors.This peptide contains an N-terminal biotin tag for easy detection and purification.
Colore e forma:PowderPeso molecolare:1,782.96 g/molANP (9-22)
ANP (9-22) 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 the cardiovascular remodelling process.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 proANP (1-126) which is converted into the circulating forms by the type II transmembrane serine protease Corin.

Shepherdin is an antagonist of the interaction between the apoptosis protein, survivin, and the molecular chaperone, heat shock protein 90 (Hsp90). The sequence of shepherdin corresponds to the site where Hsp90 binds to survivin. Shepherdin therefore has high affinity for Hsp90 and thus disrupts survivin binding and acts as an inhibitor of Hsp90 ATPase function by competing with ATP.The survivin-Hsp90 complex is a regulator of cell proliferation and cell viability in cancer tissue. Shepherdin has anti-cancer properties and can significantly suppress the growth of lung cancer cell lines and acute myeloid leukaemia (AML) by inducing apoptosis.Colore e forma:PowderPeso molecolare:948.4 g/molGurmarin

It has been shown to bind to glutamate receptors, which are ion channels that allow ions such as calcium and sodium to pass through cell membranes. Gurmarin has been shown to activate these receptors in vitro, and knockout or over-expression of these receptors in cells can lead to changes in receptor activity. Gurmarin has also been shown to have specific binding affinity for a certain type of receptor cell, which are cells with cation channels that may be involved in taste perception. The receptor binding site on the gurmarin molecule is thought to correspond with the sweet taste sensation.Formula:C187H276N46O53S6Purezza:Min. 95%Peso molecolare:4,208.95 g/molBiotin SBP1

Formula:C72H78N10O27Purezza:Min. 95%Peso molecolare:1,515.48 g/molARF peptide
ARF peptide, is the alternative frame (ARF) tumour suppressor protein which is expressed on the occurrence of oncogenic stimuli. It functions to prevent abnormal cell proliferation through inhibiting the p53 ubiquitin ligase protein Mdm2 from degrading p53. This results in the increased stability of the p53 tumour suppressor causing G1 cell cycle arrest. Additionally mouse ARF proteins can localise E2F1 and c-Myc transcriptions factors to the nucleolus therefore they are no longer able to activate S-phase promoting target gene. Again this results in cell cycle arrest, ultimately preventing tumour cell growth. It is evident that if the expression of the ARF peptide is inhibited tumour formation is more likely to occur.Colore e forma:PowderPeso molecolare:1,867.1 g/molSMRT peptide

Pathogenic Staphylococcus aureus strains produce N-formylmethionyl containing peptides. Peptides starting with an N-formylated methionyl group constitute a unique hallmark of bacterial as well as mitochondrial metabolism, and professional phagocytes of our innate immune system recognise this microbial/mitochondrial pattern as a danger signal that guides innate immune cells.All PSMα peptides have the same basic functions and promote virulence through effects on discrete neutrophil functions (i.e. chemotaxis) and by being cytotoxic at higher concentrations. PSMα2 and PSMα3 can both bind to FPR2 and trigger superoxide release in neutrophils at low nanomolar concentrations. In addition, at high nanomolar concentrations they display cytotoxicity selectively on apoptotic neutrophil membranes and this occurs in an FPR2 independent manner.Colore e forma:PowderPeso molecolare:2,304.4 g/molTetanus Toxin P30 (947-967)
Tetanus Toxin P30 (947-967) is a protein that is derived from the single-chain polypeptide neurotoxin produced by Clostridium tetani. The neurotoxins produced by Clostridium tetani are among the most potent molecules known to humankind. Once in the body, the toxin binds to the basal lamina at the neuromuscular junction. From here, the toxin is transported to inhibitory interneurons in the spinal cord, where it prevents the release of neurotransmitters, which causes spastic paralysis.
Peso molecolare:2,477.3 g/mol3x FLAG peptide
The synthetic canonical Flag sequence has been shown to be most effective with the Asp-Tyr-Lys-Xaa-Xaa-Asp motif triplicated for applications in protein analysis followed by the eight amino acids at the C-terminus of the classic FLAG sequence (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys). Due to the hydrophilic nature of the peptide the Flag tag typically resides on the surface of the recombinant protein thus minimising any effects on the function or transport of the fusion protein. The tag can be used in conjunction with other tags such as HA or myc depending on the application. FLAG is an artificial antigen to which high affinity monoclonal antibodies have been raised, therefore allowing for highly effective protein purification by affinity chromatography as well as accurate localisation of FLAG tagged proteins within living cells, or Western blots. FLAG peptide can be used to effectively purify complexes with multiple proteins as its mild purification procedure tends not to disrupt such complexes. It can be used to obtain proteins of sufficient purity for x-ray crystallography. The 3 x Flag peptide provides powerful detection and purification of recombinant proteins that has been characterised in numerous applications including affinity chromatography, binding assays and structural analysis.Peso molecolare:3,649.8 g/mol
