Description

Fsh-β-(51-65) CAS NO 135048-75-8 is a synthetic peptide fragment corresponding to a specific sequence of the beta subunit of Follicle-Stimulating Hormone (FSH). This high-purity peptide is critical for advanced biochemical research and pharmaceutical development, serving as a precise reference standard and a key intermediate. It is primarily utilized by research institutions and biopharmaceutical companies focused on endocrinology, reproductive biology, and therapeutic peptide synthesis.

Application

• Biochemical Research: Used as a reference standard in immunoassays (ELISA, RIA) and receptor binding studies to investigate FSH structure and function.
• Pharmaceutical Development: Serves as a critical intermediate in the synthesis and quality control of novel peptide-based therapeutics targeting fertility and endocrine disorders.
• Antibody Production: Acts as a specific immunogen for generating monoclonal and polyclonal antibodies against the FSH beta subunit for diagnostic applications.
• Academic Studies: Employed in university and institutional labs for fundamental research into gonadotropin signaling pathways and hormone-receptor interactions.
• Diagnostic Kit Manufacturing: Utilized as a calibrator or control in the development and validation of diagnostic kits for measuring FSH levels.
