Description

Luteinizing Hormone, Beta is a purified subunit of the glycoprotein luteinizing hormone (LH), a critical pituitary hormone. This high-purity biological material is essential for research, diagnostic development, and biopharmaceutical applications where specificity to the beta subunit is required. It is primarily utilized by biotechnology firms, diagnostic kit manufacturers, and academic research institutions focusing on reproductive endocrinology, immunoassay development, and hormone structure-function studies.

Application

• Immunoassay Development & Calibration: Serves as a critical reference standard and calibrator for ELISA and other immunoassays measuring LH levels.
• Antibody Production & Characterization: Used as an immunogen to generate highly specific monoclonal or polyclonal antibodies against the LH beta subunit.
• Reproductive Biology Research: Fundamental research tool for studying LH receptor binding, signal transduction, and its role in ovulation and steroidogenesis.
• Diagnostic Kit Manufacturing: A key raw material in the production of in-vitro diagnostic (IVD) tests for fertility monitoring and endocrine disorders.
• Pharmaceutical R&D: Used in the development and quality control of therapeutic hormones and related biopharmaceuticals.
• Biochemical Standardization: Acts as a purity and activity standard in laboratories for cross-method validation and standardization.

Quality Control

Our Luteinizing Hormone, Beta is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including purity assessment by HPLC, identity confirmation, and biological activity evaluation where applicable. We ensure compliance with relevant guidelines for biological materials. A detailed Certificate of Analysis (COA) documenting purity, potency, and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. Avoid repeated freeze-thaw cycles.
