Description

Human Serum Albumin (HSA) is a highly purified, globular protein derived from human plasma, serving as the most abundant protein in human blood. It is a critical excipient and stabilizer in biopharmaceutical formulations, valued for its ability to bind and transport a wide variety of molecules. This essential protein is primarily utilized in the pharmaceutical, diagnostic, and cell culture industries for vaccine production, therapeutic protein stabilization, and as a component in cell growth media.

Application

• Pharmaceutical Excipient & Stabilizer: Used as a stabilizer in vaccines, therapeutic proteins, and other biopharmaceuticals to prevent aggregation and denaturation.
• Cell Culture Supplement: A key component in serum-free and low-serum media formulations to support the growth and viability of mammalian cells.
• Diagnostic Reagent: Employed as a standard or blocking agent in immunoassays, clinical chemistry tests, and diagnostic kit manufacturing.
• Research & Development: Used in biochemical and pharmaceutical research for studying drug-protein interactions, osmotic pressure, and as a model protein.
• Therapeutic Use: Serves as a plasma volume expander in clinical settings for the management of shock, burns, and hypoproteinemia.
