Description

Prolactin, Human CAS NO 9002-62-4 is a vital polypeptide hormone produced by the anterior pituitary gland, playing a central role in lactation, metabolism, and immune regulation. Its high purity and biological activity are critical for reliable research and diagnostic applications. This product is essential for biotechnology firms, pharmaceutical R&D departments, and clinical diagnostic laboratories engaged in endocrinology, reproductive biology, and metabolic disorder studies.

Application

• Biomedical Research: Fundamental studies on lactation physiology, reproductive endocrinology, and the role of prolactin in immune system modulation.
• Diagnostic Kit Manufacturing: Used as a key antigen or standard in the production of immunoassay kits (e.g., ELISA, RIA) for measuring prolactin levels in human serum.
• Pharmaceutical Development: Serves as a reference standard in drug discovery programs targeting prolactin receptors for conditions like hyperprolactinemia, certain cancers, and autoimmune diseases.
• Cell Culture & In Vitro Studies: Added to cell culture media to investigate its effects on cell proliferation, differentiation, and secretory functions in various cell lines.
• Quality Control & Calibration: Acts as a primary standard for calibrating analytical instruments and validating methods in quality control laboratories.

Quality Control

Our Prolactin, Human is manufactured and tested under strict quality management systems. Each batch is characterized for identity, purity, and biological potency using advanced analytical techniques including HPLC, SDS-PAGE, and immunoassays. A comprehensive Certificate of Analysis (COA) detailing purity, endotoxin levels, and bioactivity is provided with every shipment to ensure it meets the stringent requirements of research and diagnostic applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted solutions should be aliquoted and stored at -20°C to -80°C to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use.
