KPV is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone, corresponding to residues 11-13 of the parent sequence. At three residues it is the shortest peptide in the PeptideSeed catalogue.
KPV is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone, corresponding to residues 11-13 of the parent sequence. At three residues it is the shortest peptide in the PeptideSeed catalogue.
Short sequences of this kind are unusually robust: KPV tolerates a wider pH range than most of the catalogue, dissolves almost instantly, and is comparatively resistant to enzymatic degradation in bench conditions.
Unlike the full alpha-MSH sequence, KPV carries no chromophore and produces a colourless solution. Any tint in a reconstituted vial indicates contamination and the vial should be discarded.

Vials arrive lyophilized and sealed under nitrogen. Bring the vial fully to room temperature before breaking the seal — opening a cold vial condenses atmospheric moisture onto the cake.
Direct diluent gently against the inside wall of the vial rather than onto the cake, and allow the material to dissolve without agitation. Vortexing shears longer sequences and introduces air.
Lyophilized: -20 C, desiccated. Reconstituted: 2-8 C, use within 30 days.

No. It is the terminal three-residue fragment of that sequence, supplied on its own.
Less than most of the catalogue. It dissolves readily and is stable across a broader pH range, though standard cold storage still applies.
Purification to 99% and full analytical documentation dominate the cost at this scale, not chain length.
KPV is supplied for in-vitro laboratory research only. It is not a drug, dietary supplement, food or cosmetic, is not approved by the FDA for any use in humans or animals, and no dosing guidance is published for it. Nothing on this page is a therapeutic, structure–function or health claim. Purchasers must be 21 or over and are responsible for compliance with all applicable law. Full terms of supply.
