MedKoo Cat#: 465293 | Name: Alytesin TFA
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Alytesin is a neuropeptide originally isolated from frog (A. obstetricans) skin that has diverse biological activities. It induces hypertension with tachyphylaxis and increases blood glucose levels in dogs. Alytesin reduces gastric acid secretion in rats. It also induces anorexigenic effects in neonatal chicks.
