A point of accuracy first: KPV is a peptide — specifically a tripeptide.
Its sequence is lysine–proline–valine, commonly written as Lys–Pro–Val or KPV. It corresponds to the C-terminal three-amino-acid fragment of alpha-melanocyte-stimulating hormone, α-MSH(11–13). Its short sequence and low molecular weight distinguish it from the longer-chain peptides elsewhere in the catalogue.
Supplied as lyophilised KPV at a 10mg nominal fill.

FAQ
What is KPV?
KPV is a short peptide consisting of three amino acids: lysine, proline and valine.
What does α-MSH(11–13) mean?
It identifies KPV as the three-amino-acid sequence corresponding to positions 11–13 of alpha-melanocyte-stimulating hormone.
What is the CAS number for KPV?
67727-97-3 for the free peptide.
What is its molecular weight?
342.43 g/mol for H-Lys-Pro-Val-OH. The supplied material may include counterions or residual water, so the lot-specific COA should be used for precise calculations.
Is KPV supplied for human use?
No. It is supplied strictly for laboratory research use only and is not for human consumption, medical, veterinary or cosmetic use.
