KPV Tripeptide (Lyophilized)
KPV is the C-terminal tripeptide (lysine-proline-valine) of alpha-melanocyte-stimulating hormone (α-MSH). It is supplied as a lyophilized research powder in 10mg and 20mg vials.
Research Applications
KPV is studied for its role in inflammatory signaling, including NF-κB pathway activity and cytokine expression in epithelial and immune cell models. Researchers are interested in it because it keeps much of α-MSH’s anti-inflammatory activity in a far smaller molecule.
Why Researchers Choose It
- Small, well-characterized α-MSH fragment
- 10mg and 20mg options
- Lyophilized for stability in storage and transit
- Batch-tracked with third-party COA testing

Frequently Asked Questions
Where does KPV come from?
KPV is the last three amino acids of α-MSH, a naturally occurring melanocortin peptide.
What is KPV mainly studied for?
It is mainly used in inflammation and immune signaling research.
Does this product come with a Certificate of Analysis?
Yes. Every batch is supported by independent third-party analytical testing confirming identity and purity.
What does lyophilized mean?
Lyophilized means freeze-dried. Removing water this way gives the peptide a stable powder form that holds up well in storage and shipping.
Is this product approved for human or animal use?
No. It is sold strictly for in-vitro laboratory research.
