About KPV
KPV is a synthetic tripeptide (L-lysine-L-proline-L-valine) corresponding to the C-terminal three residues of alpha-melanocyte-stimulating hormone (α-MSH 11-13). It has been characterized in the peer-reviewed peptide literature since the 1990s, with published preclinical studies investigating inflammatory-cytokine assays in macrophage cultures, IκB-α degradation pathways, and epithelial cell culture models across the peptide and immunology-research fields.
All KPV supplied by BioInfinity is manufactured by solid-phase peptide synthesis (SPPS), purified by reverse-phase HPLC, and confirmed by mass spectrometry to >99% purity. It ships as a lyophilized (freeze-dried) white powder in a septum-sealed vial, ready for reconstitution with bacteriostatic water for laboratory use.
