Kisspeptin-54 (human)

This potent endogenous ligand for the kisspeptin receptor (KISS1R/GPR54) exhibits high binding affinity for both human and rodent receptors. It is widely used in research on cancer metastasis, where it inhibits tumor cell migration and invasion in vitro, and in neuroendocrinology, where central administration stimulates gonadotropin secretion in vivo.
