Physical Properties
Kisspeptin-10 is a synthetic decapeptide corresponding to the C-terminal active fragment of the larger kisspeptin peptide family. The C-terminal amidation enhances structural stability and receptor-binding conformation under controlled research conditions. As a short-chain peptide, it is susceptible to enzymatic degradation in biological environments, 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 10–amino acid peptide fragment representing the active core sequence of longer kisspeptin peptides. It is used in research to investigate reproductive endocrine signaling and GnRH regulation pathways.
What is Kisspeptin-10 commonly researched for?
In laboratory and preclinical models, Kisspeptin-10 is studied for:
-
GPR54 (KISS1R) receptor activation
-
GnRH release signaling mechanisms
-
Hypothalamic–pituitary–gonadal axis regulation
-
Reproductive hormone pathway research
All applications are exploratory and conducted in controlled research environments.
Is Kisspeptin-10 the same as full-length Kisspeptin-54?
No. Kisspeptin-10 is a shorter fragment derived from longer kisspeptin peptides such as Kisspeptin-54. While it contains the biologically active core region, it differs in length and stability characteristics in research models.
How does Kisspeptin-10 differ from Gonadorelin?
Kisspeptin-10 acts upstream in endocrine signaling by stimulating GnRH neuron activation, whereas Gonadorelin is a synthetic form of GnRH itself. Their positions within the reproductive signaling cascade differ in research models.
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 unreconstituted 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.
How should reconstituted Kisspeptin-10 be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Gently swirl to mix; avoid vigorous agitation
Does Kisspeptin-10 require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, verifying peptide identity, purity, and analytical testing results to ensure research quality and traceability.
