Why this one
The smallest peptide in this catalog, and it earns the vial. KPV retains the inflammatory-pathway activity associated with alpha-MSH while leaving the pigmentation-related activity of the full peptide behind — a clean separation that is difficult to achieve any other way.
Runs in epithelial and immune cell culture, NF-κB and cytokine-release assays, and preclinical mucosal inflammation models. Three residues means unusually stable and easy to handle.
Where it shows up in the literature
NF-κB signallingTranscription factor activation in stimulated cell models.
Cytokine readoutsPro-inflammatory cytokine release in epithelial and immune culture.
Mucosal modelsPreclinical intestinal and epithelial inflammation research.
Minimal fragmentActivity retained relative to full-length α-MSH.

Handling
Store sealed vials at 2–8°C for short-term use, or at −20°C for long-term storage, and protect from light. Reconstitute with the diluent your protocol specifies; bacteriostatic water is the common choice where a vial will be entered more than once.
Allow refrigerated material to reach room temperature before opening, and avoid repeated freeze-thaw cycles once in solution.
Certificate of analysis
Every lot is tested by an independent ISO-accredited laboratory. The lot number on your vial resolves at the testing laboratory directly, so the purity figure never has to come from the party selling it to you.
