Description

Albumin CAS NO 266309-43-7 is a high-purity, globular protein derived from serum or other biological sources, serving as a critical functional and stabilizing agent. Its exceptional binding capacity and biocompatibility make it indispensable for formulating sensitive biological products and diagnostic reagents. This product is essential for manufacturers in the pharmaceutical, biotechnology, and in-vitro diagnostics industries requiring a reliable, high-quality protein component.

Application

• Pharmaceutical Formulations: Used as a stabilizer and excipient in vaccines, therapeutic proteins, and other injectable biologics to prevent surface adsorption and aggregation.
• Cell Culture Media: Serves as a nutrient carrier and growth promoter in serum-free and low-serum mammalian cell culture systems.
• Diagnostic Reagents: A key component in calibration standards, assay buffers, and control sera for clinical chemistry and immunoassay diagnostics.
• Biochemical Research: Employed as a standard in protein assays, a blocking agent in immunoassays (e.g., ELISA, Western Blot), and a model protein in physiological studies.
• Microbiology: Used as a supplement in culture media for fastidious microorganisms.
• Tissue Engineering: Acts as a component in hydrogels and scaffolds to enhance biocompatibility and cell attachment.

Quality Control

Our Albumin is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for purity, identity, and functionality, suitable for demanding applications. Certificates of Analysis (COA) documenting key parameters such as purity (by electrophoresis or HPLC), endotoxin levels, and biological activity are available upon request. We can supply grades compliant with relevant pharmacopoeial standards (e.g., USP, EP) for pharmaceutical use.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture. For bulk quantities, aliquot into smaller, single-use containers to minimize repeated freeze-thaw cycles and exposure.
