Description

Fsh-β-(81-95) CAS NO 132880-10-5 is a synthetic peptide fragment corresponding to amino acid residues 81-95 of the beta subunit of Follicle-Stimulating Hormone (FSH). This high-purity peptide is a critical reference standard and research tool for the study of hormone structure, function, and receptor interaction. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic manufacturers focused on reproductive endocrinology and therapeutic development.

Application

• Biochemical Research: Used as a precise antigen for mapping antibody epitopes and studying the structure-activity relationship (SAR) of FSH.
• Immunoassay Development: Serves as a critical standard and calibrator in the development and validation of ELISA and other immunoassays for FSH detection.
• Pharmaceutical R&D: Acts as a key intermediate or reference compound in the development of novel fertility treatments and hormone-based therapeutics.
• Antibody Production: Employed as an immunogen for generating highly specific polyclonal and monoclonal antibodies against FSH-β.
• Quality Control: Functions as a system suitability standard in the quality control of recombinant FSH and related biopharmaceutical products.
• Academic Studies: Facilitates fundamental research in endocrinology, exploring hormone-receptor binding mechanisms and signal transduction pathways.
