Description

Chorionic Gonadotropin B-Subunit Fragmen T 109-119 Amide is a synthetic peptide fragment corresponding to a specific sequence of the β-subunit of human chorionic gonadotropin (hCG). This compound is a critical research tool for studying hormone-receptor interactions, immunological responses, and the development of diagnostic assays. It is primarily utilized by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on endocrinology, immunology, and therapeutic development.

Application

• Biochemical Research: Used as a reference standard and antigen in studies of hCG structure, function, and receptor binding mechanisms.
• Immunoassay Development: Serves as a key antigen for the production and calibration of antibodies in diagnostic test kits for pregnancy and related disorders.
• Vaccine Research: Investigated as a potential component in immunocontraceptive and cancer vaccine research due to its specific immunological properties.
• Peptide Synthesis & Conjugation: Acts as a building block or hapten for creating larger peptide constructs or carrier protein conjugates for immunological studies.
• Quality Control: Employed as a system suitability standard in the pharmaceutical quality control of hCG-related products.

Quality Control

Our peptide products are manufactured and analyzed under strict quality management systems. Each batch of Chorionic Gonadotropin B-Subunit Fragmen T 109-119 Amide undergoes comprehensive testing including HPLC for purity, MS for identity confirmation, and amino acid analysis. Certificates of Analysis (COA) detailing all specifications are provided to ensure compliance with research-grade standards and support your regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. For long-term storage, keep desiccated under inert atmosphere.
