Physical Properties
Kisspeptin-10 is a synthetic decapeptide corresponding to the C-terminal 10 residues of kisspeptin-54. The C-terminus is amidated. As a short-chain peptide, it is susceptible to enzymatic degradation, making lyophilized storage and cold-chain handling important for preserving structural integrity. Protection from moisture, light exposure, and repeated freeze–thaw cycles helps maintain analytical consistency during laboratory applications.

Frequently Asked Questions
What is Kisspeptin-10?
Kisspeptin-10 is a synthetic decapeptide with the sequence Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH₂ (molecular formula C₆₃H₈₃N₁₇O₁₄, molecular weight ~1,302.5 Da). It is supplied as a white to off-white lyophilized powder.
Is Kisspeptin-10 the same as full-length Kisspeptin-54?
No. Kisspeptin-10 is the 10-residue C-terminal fragment of kisspeptin-54 (metastin). Because it contains only those ten residues, it has its own molecular formula (C₆₃H₈₃N₁₇O₁₄) and molecular weight (~1,302.5 Da).
How is Kisspeptin-10 supplied?
Kisspeptin-10 is typically supplied as a lyophilized (freeze-dried) powder in sealed research vials to preserve stability during storage and transport.
How should lyophilized Kisspeptin-10 be stored?
Lyophilized Kisspeptin-10 should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
Does Kisspeptin-10 require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch of Kisspeptin-10, verifying identity, purity, and analytical testing results to ensure research quality and traceability.
Is Kisspeptin-10 FDA-approved?
No. Kisspeptin-10 is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
