What is KPV?

KPV (Lys-Pro-Val) corresponds to residues 11-13 of alpha-melanocyte-stimulating hormone, the smallest fragment reported to retain meaningful biological activity from the parent peptide. Because it lacks the sequence responsible for melanocortin receptor-driven pigmentation, researchers use it to isolate alpha-MSH’s anti-inflammatory effects from its pigment-related actions.

This listing is KPV (10 vials × 10mg) from SSRBIO (China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

KPV is studied for its ability to enter cells via the PepT1 peptide transporter, which is highly expressed in intestinal and skin tissue, and to inhibit NF-kB signaling once inside, reducing production of pro-inflammatory cytokines. Some in vitro work also describes direct antimicrobial activity against certain bacterial strains.

Research status

The tripeptide has been examined mainly in cell culture and rodent models of colitis, inflammatory bowel conditions, dermatitis and wound healing; it has not been evaluated in registered human clinical trials, and its transporter-dependent uptake means results can vary meaningfully between tissue types used in different study models.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Request the batch COA · How group testing works

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Specifications

Compound: KPV
Also known as: Lys-Pro-Val, alpha-MSH(11-13)
Class: Naturally occurring tripeptide, C-terminal alpha-MSH fragment
Form: Lyophilized (freeze-dried) powder
Sequence: Lys-Pro-Val
Per vial: 10mg
Units per kit: 10
Brand: SSRBIO · China

Handling & storage

Supplied as a lyophilized powder; store unopened vials at -20C protected from light, and once reconstituted with bacteriostatic water keep refrigerated at 2-8C for use within the study’s defined timeframe.

Concentration check: adding 2 ml of bacteriostatic water to one 10mg vial gives 5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

How does KPV differ from full-length alpha-MSH?

KPV retains only the three C-terminal residues of alpha-MSH and lacks the N-terminal sequence responsible for melanocortin receptor binding and pigmentation, so research models use it to study anti-inflammatory activity separately from pigment-related signaling.

What should a COA confirm for KPV?

Sequence identity (Lys-Pro-Val), molecular weight near 342 g/mol, and HPLC purity of 99% or higher, ideally from an independent lab given how short and easily miscategorized tripeptides can be on lower-resolution testing.

How much KPV is in this kit?

10 vials of 10mg each. The lab testing section above shows what the brand’s tested sample actually contained, where a report exists.
