Description

Hypophysin is a complex polypeptide hormone preparation derived from the posterior pituitary gland, primarily known for its vasopressin and oxytocin activity. This product is critical for research and development in endocrinology and for the formulation of specialized pharmaceutical intermediates. It serves the needs of biotechnology firms, academic research institutions, and pharmaceutical manufacturers engaged in hormone-related studies and therapeutic development.

Application

• Biomedical Research: Used as a reference standard and active component in studies investigating the physiological roles of vasopressin and oxytocin.
• Pharmaceutical Intermediates: Serves as a key starting material in the synthesis and development of hormone-based therapeutics.
• Endocrinology Studies: Essential for in vitro and in vivo research models focusing on pituitary function, water balance, blood pressure regulation, and uterine contraction.
• Diagnostic Reagent Manufacturing: Employed in the production of diagnostic kits and assays designed to measure related hormonal pathways.
• Veterinary Medicine: Applied in research for developing treatments related to reproductive health and fluid balance in animals.
