KPV

α-MSH C-terminal tripeptide · 10-vial research kit

Tripeptide (lysine–proline–valine)

KPV is a tripeptide (lysine-proline-valine) corresponding to the C-terminal fragment of α-MSH. It is studied for its role in inflammation and cellular-signalling research.

About KPV

KPV is a three–amino-acid peptide (lysine-proline-valine) corresponding to the C-terminal sequence of α-melanocyte-stimulating hormone (α-MSH). It is studied in inflammation and cellular-signalling research and is supplied as a lyophilized 10-vial kit.

RetaNord supplies KPV as fixed kits of 10 or 30 lyophilized vials, each verified at 99%+ identity purity by independent third-party HPLC (Janoshik), and every kit ships with a lot-specific Certificate of Analysis. Supplied for laboratory and in vitro research use only.

How KPV works

KPV is the C-terminal tripeptide of α-melanocyte-stimulating hormone — lysine-proline-valine, the last three residues of α-MSH.

Published work reports that this short fragment retains much of the parent hormone’s anti-inflammatory activity while lacking the pigmentary activity of the full sequence. Being three residues long, it is also small enough for delivery routes that a larger peptide cannot use.

Mechanistic summary drawn from published literature, provided for research context only. Not a therapeutic claim.

What the research shows

The 2003 Journal of Pharmacology and Experimental Therapeutics paper dissected which part of α-MSH carries the anti-inflammatory effect; later work extends this into epithelial and delivery models.

The literature is preclinical. KPV is not an approved medicine.

Storage & handling

Sealed, lyophilized vials. 2–8 °C for routine storage; −20 °C or below for long-term. Room temperature is for transit and handling only — it is not a storage state for a peptide.

Once reconstituted. Keep at 2–8 °C and never freeze — ice crystals cause irreversible damage. Reconstituted with bacteriostatic water (0.9% benzyl alcohol) a vial is commonly used within about 30 days; with plain sterile water, within 24–48 hours.

Keep vials sealed and protected from light, and minimise freeze–thaw cycles of frozen stock — each cycle costs potency.

KPV — questions

Do the kits come with a Certificate of Analysis?

Yes — every kit ships with a lot-specific third-party Certificate of Analysis: independent HPLC purity and content testing by Janoshik, with the batch matching your vials. View the current CoA.

What does KPV stand for?

The three amino acids it is made of: lysine (K), proline (P) and valine (V). It is the C-terminal fragment of α-MSH. Supplied for laboratory research use only.

Why is this sold as a 10-vial kit?

These research compounds are supplied in fixed kits of 10 identical vials — the standard research quantity. One kit (10 vials) is the minimum order to the EU.

How should KPV be stored?

Sealed lyophilized vials keep at 2–8 °C, or −20 °C for long-term storage. Once reconstituted, keep refrigerated and never freeze it. See storage & handling for the full detail.

How do I work out the concentration?

The volume of bacteriostatic water you add sets the concentration — the vial size alone does not. Enter your vial size and diluent volume in the reconstitution calculator to calculate the concentration for your assay.

Does KPV cause pigmentation like α-MSH?

The published work reports that the KPV fragment retains anti-inflammatory activity without the melanocortin pigmentary activity of the full α-MSH sequence. It is studied in inflammation research, not pigmentation research.
