Kisspeptin-10: The Kiss1 Receptor Ligand in GnRH Research

Research compounds for laboratory use only · not medical advice

Kisspeptin-10, the C-terminal decapeptide of Kiss1/metastin, and its research in reproductive neuroendocrinology, GnRH pulsatility and KISS1R pharmacology.

Kisspeptin-10 has one of the most memorable names in peptide research, and one of the clearest jobs: it is the ligand that sits upstream of the reproductive hormone cascade, and its discovery rewired how reproductive neuroendocrinology is understood.

The molecule

Kisspeptin-10 is the C-terminal decapeptide (C₆₃H₈₃N₁₇O₁₄, ≈ 1302 g/mol) of the Kiss1/metastin peptide family. It is the high-affinity endogenous ligand of the GPR54 receptor (KISS1R). The gene was named for Hershey’s Kisses — the candies made in Hershey, Pennsylvania — a naming story from the original 2001 Nature discovery paper by Ohtaki and colleagues.

What the research looks at

  • GnRH pulsatility and puberty — kisspeptin is a master regulator of GnRH neuron activity; puberty onset research is a core thread
  • Reproductive neuroendocrinology — the kisspeptin-GnRH-GnIH axis
  • KISS1R receptor pharmacology — binding and signaling studies for GPR54

Handling notes

Lyophilized, reconstitute with bacteriostatic water; the reconstitution calculator handles the math. Store at −20°C lyophilized.

FAQ

Frequently asked questions

What is Kisspeptin-10?

Kisspeptin-10 is the biologically active C-terminal decapeptide of the Kiss1/metastin peptide family, acting as a high-affinity ligand of the GPR54 (KISS1R) receptor.

What research uses Kisspeptin-10?

Reproductive neuroendocrinology, GnRH-pulsatility and puberty research, and kisspeptin-receptor pharmacology.

Why is it called Kisspeptin?

The Kiss1 gene was named for Hershey's Kisses — the candies in Hershey, Pennsylvania, where the gene was discovered (Ohtaki et al., Nature, 2001).
