Chemical identity

What KPV is

KPV is the tripeptide L-lysyl-L-prolyl-L-valine (H-Lys-Pro-Val-OH), a synthetic linear tripeptide whose sequence corresponds to residues 11-13 of alpha-MSH (the C-terminal Lys-Pro-Val segment), so it is also catalogued as alpha-MSH(11-13) or ACTH(11-13). The free peptide has the molecular formula C16H30N4O4 and a molecular weight of 342.43 g/mol (PubChem CID 125672, CAS 67727-97-3), matching the Pepta Labs listing (342.44 Da). KPV carries a free N-terminal amine, a lysine side-chain amine and a free C-terminal carboxylic acid; commercial material is usually the acetate salt (H-Lys-Pro-Val-OH.AcOH) or the trifluoroacetate salt. Pepta Labs supplies KPV as a lyophilized powder in a sealed glass vial (10 mg quantity) with reported RP-HPLC purity and mass-spectrometric identity. Store at 2-8 C on arrival or at -20 C for long-term storage, away from light and moisture. Laboratory research use only.

Questions

KPV 10mg — common questions

What sizes of KPV does Pepta Labs sell?

One: KPV 10mg, a sealed glass vial holding a supplier-stated 10 mg of lyophilized powder. Pepta Labs does not list a larger or smaller KPV vial, so more material means ordering more of the same 10 mg vial; the pack options on this page show the multi-vial choices.

What is in a KPV 10mg vial as supplied?

A supplier-stated 10 mg of KPV as dry, freeze-dried powder in a sealed glass vial, with no liquid in the vial. The 10 mg figure is the stated quantity of material, not a measured content: net peptide content (the share of the powder that is peptide rather than counter-ion and residual water) is not reported per listing, and the vial carries no lot number.

Is KPV sold as the acetate or the TFA salt?

Commercial KPV is usually the acetate salt (H-Lys-Pro-Val-OH.AcOH) or the trifluoroacetate (TFA) salt, and this listing does not state which counter-ion the sourced production run carries. If the salt form matters for your work, ask support@peptalabs.com before ordering. The counter-ion adds to the weight of the powder in the vial; the Learn guide TFA vs Acetate Peptide Salts explains how that affects the stated quantity.

How do I get the KPV certificate of analysis (COA) before buying?

Request it on this page or email support@peptalabs.com with the name KPV 10mg, and the report is sent by email, before you order if you want it. It covers the sampled production run rather than an individual vial: purity is given as RP-HPLC area-% and identity is confirmed by mass spectrometry. The Learn guide How to Read and Verify a Peptide Certificate of Analysis walks through each field of the report.

How should sealed KPV powder be stored?

Keep the vial sealed and dry: refrigerate at 2-8 °C on arrival, or hold at -20 °C for longer storage, away from light and moisture. The powder ships at ambient temperature with no cold pack. The Learn guide Storage Temperature and Handling of Lyophilized Research Peptides covers dry-powder storage in more depth.

What does KPV 10mg cost?

KPV 10mg starts at $39.35 per vial. 3-vial packs are 7% off and 5-vial packs are 14% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. KPV 10mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What does the name KPV stand for?

K, P and V are the one-letter codes for lysine, proline and valine, so KPV is the tripeptide Lys-Pro-Val (C16H30N4O4, 342.43 g/mol, CAS 67727-97-3).

Is KPV the same as alpha-MSH(11-13)?

Yes. Lys-Pro-Val is the sequence of residues 11 to 13 of alpha-MSH, so PubChem lists alpha-MSH(11-13) and ACTH(11-13) as synonyms of the same tripeptide (CID 125672). The synthetic material is the isolated tripeptide with a free acid C-terminus, not the parent 13-residue peptide.

What is the expected mass on the analytical report?

The monoisotopic mass of the free tripeptide is 342.23 Da and the average molecular weight is 342.43 g/mol; in ESI-MS the [M+H]+ ion is expected near m/z 343.2. Acetate or trifluoroacetate counter-ions are not part of this mass.
