About KPV in research
KPV is the carboxy-terminal tripeptide of α-melanocyte-stimulating hormone (α-MSH), comprising Lysine-Proline-Valine. The fragment has been studied in laboratory models for its observed interactions with NF-κB and downstream cytokine signaling, with reports across in vitro epithelial and immune-cell systems. As a short, sequence-defined tripeptide, KPV is a frequent reference standard in identity and purity work.
Why labs source identity-forward KPV
Procurement teams reviewing KPV typically check three things: confirmed sequence by mass spectrometry, HPLC purity at or above 99%, and a published net-peptide content (peptide-bound water and counter-ion removed). Our listing is structured so a buyer can attach a SKU- and lot-level certificate of analysis to a purchase order without manual reformatting.
Storage and laboratory handling
Lyophilized KPV is shipped in clear borosilicate vials with a butyl stopper and aluminum overseal. For long-term storage, hold sealed vials at -20 °C protected from light. After reconstitution in bacteriostatic water or another lab-grade buffer, store at 2-8 °C and use within the working window your protocol specifies. Avoid repeated freeze/thaw of reconstituted aliquots.
Documentation supplied
Each shipment can be paired with a third-party certificate of analysis covering identity (MS), purity (HPLC), net-peptide content, and a moisture/residuals summary where in scope. Batch records are filed against the SKU so compliance teams can retrieve them in audit format.

Storage and handling
Handle KPV as a lyophilized research reagent: cold, dry, light-protected storage; choose reconstitution buffer per your SOP; plan aliquots to limit freeze–thaw; and keep the lot CoA with the inventory record.
Research framing
Use KPV in published model-system terms only — receptor family, pathway context, assay controls, and concentration planning. Do not transfer assumptions from adjacent peptides without a documented comparison protocol. Research use only.

Product FAQ
Is KPV intended for human or clinical use?
No. BluGen listings are research use only (RUO) for qualified laboratory programs — not clinical, diagnostic, therapeutic, veterinary, food, drug, or cosmetic use.
What documentation ships with KPV?
Each lot includes a certificate of analysis with HPLC purity, MS identity confirmation, and net peptide content. Verify lots in the CoA Library.
Where can I verify the current-lot CoA for KPV?
Search by compound or lot number in the CoA Library: https://getblugen.com/coa-library/
What sequence is listed for KPV?
The listed sequence is H-Lys-Pro-Val-OH. Confirm against the lot-specific CoA before release into inventory.
How should lyophilized KPV be stored?
Store sealed vials cold, dry, and protected from light per the lot CoA and your institutional SOP. Aliquot reconstituted stock to limit freeze-thaw cycles.
Can institutions request a quote for KPV?
Yes. Academic labs and CROs can request quotes and NET-30 billing after vendor qualification via the contact/procurement desk.
