Fmoc-Phe-Ser(Psi(Me,Me)Pro)-OH
CAS:Fmoc-Phe-Ser(Psi(Me,Me)Pro)-OH is a diastereomer of Fmoc-Phe-Ser. It is used as a substrate for peptide synthesis and can be used to synthesize oxytocin receptor antagonists. It has been shown to have high affinity for the oxytocin receptor and inhibits the binding of oxytocin to the receptor by competing with it for the same site on the receptor. This inhibition leads to decreased levels of oxytocin that are responsible for uterine contractions during labour and milk ejection from the breast during breastfeeding. Fmoc-Phe-Ser(Psi(Me,Me)Pro)-OH also has been shown to be useful in filtration techniques such as chlorides, propargylamines, and divalent cyclopentenones.Fórmula:C30H30N2O6Pureza:90%Forma y color:White PowderPeso molecular:514.57 g/molLL-37 amide trifluoroacetate

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 (476-490) is an epitope candidate with various predicted HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.Peso molecular:1,658.9 g/molEndothelin-1 (Human) Antiserum
Endothelin-1 (ET-1) is a peptide hormone that stimulates the release of catecholamines from the adrenal medulla, and acts as a vasoconstrictor.

ClickBMVgag7-25
Brome mosaic virus (BMV) Gag peptide (7-25) has been utilised as a cell penetrating peptide (CPP). Translocation across the cell membrane with a cargo molecule varies in effectiveness depending on the CPP. BMV Gag (7-25) has a very high efficiency of internalisation which has been linked to the high percentage of arginine residues present.BMV Gag (7-25) 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-BMV Gag (7-25) allows a wide variety of applications particularly for conjugation, modification, and peptide design.Forma y color:PowderLL-37 acid
LL-37, also known as CAP-18 for Cathelicidin antimicrobial peptide 18, is a 37 amino acid cationic peptide. LL-37 is also a typical linear antimicrobial peptide which can eliminate a wide range of pathogenes, including bacteria, viruses, fungi, and parasites. LL-37 is the only human cathelicidin peptide reported yet, found in lysosomes of macrophages and leukocytes. LL-37 plays an important role in the first act of defense against local infection and systemic invasion of pathogens at sites of inflammation. LL-37 shows cytotoxicity against bacterial and normal eukaryotic cells and is significantly resistant to proteolytic degradation. Besides its antimicrobial functions, LL-37 also has immunomodulatory roles. LL-37 suppresses the production of pro-inflammatory cytokines, TNF-α and IL-6 in infected monocytes.

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 and circulates as a biologically active 42-amino acid peptide. 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.Forma y color:PowderPeso molecular:4,980.5 g/molGIP (Pro 3)
