KPV: C-terminal fragment of alpha-MSH, the tripeptide Lys-Pro-Val

The catalog describes KPV as the tripeptide Lys-Pro-Val, the C-terminal fragment of alpha-MSH. The letters of the trade name are, literally, the abbreviation of the three amino acids that make up the sequence: lysine (K), proline (P), and valine (V). It is one of the catalog's most direct classifications, because the name itself matches the declared structure.

The reference to alpha-MSH describes which larger protein the fragment comes from, a structural classification detail. The exact identity of each lot — whether it does in fact correspond to that three-amino-acid sequence — is confirmed with the corresponding certificate of analysis, not with this general description.

Why the catalog does not group KPV with the melanocortin analogs

Alpha-MSH is also the origin of three other catalog references: MT-1, MT-2 (Melanotan 2 Acetate), and PT-141, which the site groups separately, in its own melanocortin analogs category. KPV shares that same structural origin with those three — all derive from the same hormone — but the catalog does not group them together: KPV remains within Immunomodulation, longevity, and cellular metabolism, the site's largest category.

That separation is a thematic classification decision, not a denial of the structural relationship. Anyone researching alpha-MSH-derived fragments and analogs as a group should check both catalog categories, because the grouping criterion here does not strictly follow molecular origin but rather the research axis each reference is associated with.

KPV within a category of 15 references

Immunomodulation, longevity, and cellular metabolism is, with 15 references, the catalog's largest category after Other catalog compounds. Within that group, KPV shares a research axis with mitochondrial peptides, coenzymes, and other bioregulators of very different structures.

Price differences within this category do not depend on any quality hierarchy: each reference has its own structure, its own presentation, and its own per-lot documentation process. The list price reflects sourcing and catalog factors, not a purity or documentation scale.

A 10 mg presentation and physical form

KPV is offered in a single presentation, a 10 mg vial, with internal reference code KP10. Like every specification declared in milligrams in this catalog, its physical form is lyophilized powder in a vial.

With no second presentation, the quote is limited to confirming the name KPV and the number of vials required. It is still worth including the code KP10 on the order when the institution manages several catalog references at the same time, to reduce the margin for error in the receiving record.

Janoshik COA per lot and storage

The certificate of analysis for KPV is issued by Janoshik Analytical, with HPLC for purity and MS for identity, per lot rather than for the reference in general. Access is on request and subject to document availability; this listing does not state a purity percentage in advance, because that figure belongs to the specific certificate for the lot shipped.

The storage condition the site declares for the peptide catalog is 2–8 °C, protected from light, applicable when KPV's lot documentation confirms it. The internal record can note the lot, the date of receipt, and the code KP10 alongside the reference's full name.

Quoting, shipping, and payment

Shipping cost varies by destination and is shown on the site's shipping information page. The total quote adds KPV's list price, the number of vials requested, and the shipping cost according to destination. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.

Payment is arranged after confirming reference, presentation, units, destination, and total in writing. Delivery timing is confirmed when requesting a quote, based on inventory availability.
