Human albumin

Human albumin (CAS 70024-90-7), also referred to as HSA, is a plasma-derived protein sourced from human blood and processed under stringent fractionation conditions.

Where is Human albumin used?

• Pharmaceutical and biotechnology manufacturing: stabilizer, carrier, and buffering agent
• Injectable drug formulations: stabilizes active proteins and peptides against aggregation and degradation during processing, freeze-drying, and storage
• Cell culture media for biopharmaceutical production: supports cell viability and regulates osmotic balance in serum-free and low-serum systems
• Vaccine and biologic manufacturing: excipient that protects sensitive antigens and recombinant proteins from surface adsorption and thermal stress
• Diagnostic reagent kits and in vitro assay systems: blocking agent and reference standard for calibration
• Pharmaceutical-grade material is manufactured to Ph. Eur., USP, and BP monograph standards.

Good to know: Recombinant HSA grades are available for applications requiring pathogen-free sourcing.

Commercial specifications

• Sterile aqueous solution, typically at 4%, 5%, 20%, or 25% concentrations
• Bulk supply for industrial bioprocessing
• Lot-specific documentation including viral safety testing and protein purity data
