KPV (10MG)

KPV — the C-terminal tripeptide (L-lysine-L-proline-L-valine) of the alpha-melanocyte-stimulating hormone (α-MSH) sequence — supplied by BioFusion as a vacuum-sealed lyophilized vial of 10mg for melanocortin-pathway research chemistry.

Research context

KPV is the minimal C-terminal fragment (α-MSH 11-13) of the thirteen-residue α-MSH sequence. It is studied as a compact reference compound in melanocortin-signaling and cellular-pathway research, retaining the C-terminal tripeptide motif while lacking the pigmentary receptor activity of the full-length α-MSH sequence.

Synthesis & documentation

Produced by solid-phase peptide synthesis using Fmoc protecting-group strategy in a U.S.-based ISO 9001:2008 facility. Each lot is verified for identity (LC-MS), purity (reverse-phase HPLC-UV ≥99.0%), moisture (Karl Fischer), and counter-ion (ion chromatography).

Storage & handling

Lyophilized KPV is stable at −20 °C for the printed shelf life. After reconstitution, the standard 14-day-at-2-8 °C reference window applies; avoid freeze-thaw cycling. As a tripeptide it is highly soluble and dissolves cleanly in bacteriostatic water or saline; the reconstitution calculator handles concentration math.

Why BioFusion

Short tripeptides are inexpensive to synthesize and are frequently shipped without the identity and purity verification applied to larger peptides, so by-product and counter-ion content go unchecked. BioFusion runs the same full LC-MS, HPLC, Karl Fischer, and ion-chromatography panel on KPV as on every other reference compound. Bulk discounts trigger at three+ vials; members save 25% on every order plus complimentary U.S. shipping for 365 days.
