KPVNasalSpray

KPV nasal spray in Canada is supplied by Horizon Peptides as a pre-prepared 10 mg research spray bottle, available singly or in 3-bottle and 5-bottle packs. KPV is a tripeptide fragment of alpha-melanocyte-stimulating hormone studied in inflammatory-signalling models.

KPV is named directly for its three residues, lysine, proline and valine, and corresponds to the carboxyl-terminal end of alpha-MSH. With a molecular weight of 304.37 it is among the smallest sequences stocked, and that size is central to why it is studied: researchers use it to ask how much of the parent hormone’s signalling survives in so short a fragment.

Notably, the fragment does not carry the pigmentation-associated activity of full-length alpha-MSH. That separation lets laboratories examine one branch of the hormone’s described signalling in isolation from another.

Its brevity also makes it a convenient control in comparative studies. Where a longer sequence produces a signal, running the three-residue fragment alongside it helps establish how much of that signal depends on the larger structure.
