    Product Description

    Kisspeptin-234 is a peptide antagonist of the kisspeptin receptor, previously known as G protein-coupled receptor 54 (GPR54).1 It inhibits kisspeptin-10-induced inositol phosphate production in CHO cells expressing the human kisspeptin receptor (IC50 = 7 nM) and kisspeptin-10-induced firing of isolated mouse gonadotropin-releasing hormone (GnRH) neurons. In vivo, kisspeptin-234 inhibits pulsatile GnRH secretion in pubertal female rhesus monkeys. It also inhibits kisspeptin-10-induced luteinizing hormone secretion in adult male rats and mice.
