Kisspeptin
KISS1-derived peptide
Kisspeptin-10 (KISS1-derived decapeptide)
Research context
Kisspeptin-10 is the C-terminal decapeptide of the KISS1 gene product and the minimum sequence retaining full activity at the KISS1R (GPR54) receptor. Research examines GnRH neuron activation, gonadotropin release in pituitary preparations, and receptor binding.
Common assays: KISS1R binding · GnRH neuron electrophysiology · LH release in pituitary preparations

Common questions
Why is the 10-residue fragment used rather than full-length kisspeptin?
Kisspeptin-10 is the shortest fragment retaining full KISS1R activity in published characterisation, making it the standard research form.
What receptor does kisspeptin act at?
KISS1R, also designated GPR54 — a G protein-coupled receptor expressed on GnRH neurons.
Where can I see the Kisspeptin certificate of analysis?
Every published Kisspeptin lot has its own certificate page on this site, listed under "Kisspeptin COA" above. There is one published lot; the most recent, lot KIS5VCS0526, was reported on 2026-05-21 at >99.2% purity by HPLC-UV. The certificates are issued by AxisPharm, LLC, an independent laboratory.
