KPV is a synthetic tripeptide composed of the amino acids Lysine (K), Proline (P), and Valine (V). It represents the C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH) and has been studied in the context of anti-inflammatory peptide research. Heartland Bio Labs supplies KPV as a high-purity lyophilized compound for qualified research applications.

KPV has been investigated in preclinical research models exploring inflammatory pathway modulation, gut epithelial cell signaling, and mucosal tissue biology. As a fragment of α-MSH, it is studied for its interaction with melanocortin receptors in cellular models. Published literature includes investigations of KPV activity in intestinal inflammation models and epithelial and connective tissue cell studies.

This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.

Handling Information

KPV should be handled under standard laboratory conditions using appropriate PPE. Due to its small size as a tripeptide, careful handling to minimize loss is recommended. Avoid contamination and repeated freeze-thaw cycles once reconstituted. This compound is intended for qualified research use only.

Storage Requirements

  • Long-term (lyophilized): Store at -20°C, protected from light and moisture
  • Short-term (reconstituted): Store at 4°C; use within 28 days
  • Keep in original sealed vial until point of use

How should I store this peptide?+

Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.

What should I reconstitute it with?+

Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.

How quickly do orders ship?+

Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.

Is the COA verified independently?+

Yes. Every lot is tested by HPLC for purity (target ≥99%) and mass spectrometry for molecular identity before release. The COA is generated from the actual lot data, not a generic template.

Can I get bulk or institutional pricing?+

Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
