KPV

KPV, also published as α-MSH (11–13) and Lysine-Proline-Valine, is catalogued here as: Tripeptide (Lys-Pro-Val), C-terminal fragment of α-MSH. Studied in human cell lines and mouse intestinal-inflammation models for peptide transport and inflammatory signalling. A three-part peptide studied in the lab for how intestinal cells take it up and respond to inflammation-related signals.

Cells literature: PepT1-mediated uptake of KPV was associated with reduced NF-κB/MAP kinase signalling and pro-inflammatory cytokine secretion. Human cell lines, not human participants.

Animal literature: Inflammatory markers were reduced in DSS- and TNBS-induced mouse colitis models. These induced models do not establish treatment effects in human intestinal disease.

When comparing published work, match the exact molecular identity, salt form and strength to the paper. Findings in cell or animal models describe those models only and do not establish outcomes in people. The reconstitution calculator converts vial content and diluent volume into concentration for laboratory preparation.

Proof Line Peptides lists KPV as a vial in 5 mg and 10 mg, with pack sizes of 1, 3, 5 and 10. Prices are shown in Canadian dollars, and orders ship from Toronto by tracked Canadian service.

The matched Testides report for KPV 10 mg (report BW-KPV-10mg-050926-01, dated May 18, 2026) records 99.74% purity and 10.24 mg measured content against a 10 mg label. It documents the supplier sample sent for testing, not every shipped lot, and the original PDF is linked on this page.
