Kisspeptin 13 inhibits glucose-induced insulin secretion with an IC50 of 1.2 nM. Kisspeptin 13 activates the hypothalamic-pituitary-adrenal (HPA) axis, causes hyperthermia, motor behavior and anxiety in rats. Kisspeptin 13 interacts with α2-adrenergic and 5-HT2 serotonin receptors, exhibits antidepressant efficacy. Kisspeptin 13 is an activator for GPR54 and GnRH receptor, which enhances memory and can be used in Alzheimer's disease research.

Threonine is an essential amino acid in humans. It is abundant in human plasma particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. Threonine is an immunostimulant which promotes the growth of thymus gland. It also can probably promote cell immune defense function.

Amine-PEG3-Biotin can be used as a signal amplification label.
