S413-PV-[Cys(Npys)].

Cell-penetrating peptides (CPPs) have the ability to cross cell membrane bilayers without causing lethal membrane damage. CPPs themselves can exert biological activity and can be formed endogenously, or alternatively they can enhance transport of different cargoes across cell membranes. Vascular endothelial-cadherin-derived peptide (pVec) is an amphipathic CPP, these are characterised by both hydrophobic and hydrophilic regions. The charged region interacts with the cell membrane, while the hydrophobic region causes membrane perturbation, enabling translocation. pVec is derived from vascular endothelial cadherin, which is able to cross the blood brain barrier. Peptide is labelled with an N-terminal 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag.

HLA-A*02 is a class I major histocompatibility complex (MHC) allele which is part of the HLA-A group of human major histocompatibility complex (MHC) leukocyte antigens (HLA). HLA-A is a human MHC class I cell surface receptor and is involved in presenting short polypeptides to the immune system. These polypeptides are typically 7-11 amino acids in length and originate from proteins being expressed by the cell. Cytotoxic T cells in the blood "read" the peptide presented by the complex and should only bind to non-self peptides. If binding occurs, a series of events is initiated culminating in cell death via apoptosis. Hepatitis B virus (HBV) polymerase is a multifunctional enzyme that can use both RNA and DNA as a template for amplification and also has an RNase H function. First the polymerase acts on the HBV pre-genomic RNA (pgRNA) to reverse transcribe it to form the (-) DNA strand. Simultaneously the RNA template is degraded by the polymerases RNase H activity, except for a stretch of RNA at 5' end of the pgRNA which is used to prime the synthesis of the (+) DNA strand. This process results in a new partially double-stranded relaxed circular DNA molecule (rcDNA) within a new capsid.

H-Gly-Pro-Hyp-OH is a collagen gel that is extracted from bovine skin. Collagen gel is a dietary supplement that can be applied to wounds and burns to promote healing. Collagen gel contains the amino acids glycine, proline, hydroxyproline, and hypochlorous acid. It also has an anti-inflammatory cytokine called IL-10. Hydrogen bonds form between the amino acids in collagen gel to give it its strength and stability. The LC-MS/MS method was used to identify the sequences of this peptide in order to confirm its identity. Collagen gel is neutral at pH 7 and has no effect on cellular function at this pH. The carboxy terminal of collagen gel is trifluoroacetic acid which can cause liver cells to die when ingested orally or intravenously due to its toxicity.

Ara h 3 is one of the major allergens from peanut (Arachis hypogaea) out of approximately 13 potentially important allergens described. The Ara h 3 allergen is recognised by serum IgE from approximately 45% of peanut allergy patients.The peanut (Arachis hypogaea) is a member of the legume (Leguminosae) family, which includes beans and peas. Ara h 3 belongs to the glycinin family of legume storage proteins (S11 plant storage proteins) and is extensively proteolytically processed. This peptide represents a trypic peptide of Ara h 3.

H-Gly-Arg-AMC hydrochloride salt is a substrate for the enzymes cathepsins B, H, and L. This compound has been used to measure protease activity in cell culture and as a diagnostic substrate for peptidases. The enzyme reaction can be monitored by measuring changes in the fluorescence of the product at 340 nm. The pH optimum for this enzyme is 7.4.
