How to use

In Vitro:

Half-maximal effective concentrations (EC50) for mobilization of [Ca2+]i are 9.4 nM, 3.2 nM, and 3.0 nM for human, rat, and mouse Neuropeptide S (NPS), respectively. Neuropeptide S human (4 pM to 1.7 nM; 48 hours) retains full agonist activity with an EC50 of 6.7 nM, the binding of [125I] Y10-hNPS to CHO cells stably expressing hNPSR is saturable with high affinity (Kd = 0.33 nM). Neuropeptide S human (1 pM-3 μM; 48 hours) are used to compete with 0.15 nM [125II] Y10-NPS, [125II] Y10-NPS is displaceable by increasing concentrations of human NPS (IC50 = 0.42 nM).

In Vivo:

Neuropeptide S human (0.1 nM-1 nM; i.c.v.) causes a significant increase in locomotor activity, the total distance traveled, percentage of time moving, number of rearing events, and center entries are also significantly increased in mice.
