Description

Albumin, Bovine is a high-purity, globular protein derived from bovine serum, serving as a critical reagent and stabilizer in life science research and biopharmaceutical manufacturing. Its primary value lies in its ability to bind and transport a wide variety of molecules, stabilize enzymes and other proteins, and function as a blocking agent in immunoassays. This makes it an essential component for diagnostic kit manufacturers, cell culture laboratories, and vaccine producers who require a reliable, consistent, and high-quality protein source for their processes.

Application

• Cell Culture & Vaccine Production: Used as a nutrient and stabilizer in serum-free and low-serum media formulations to support the growth of mammalian cells.
• Diagnostic Reagents & Immunoassays: Serves as a standard protein, a blocking agent to reduce non-specific binding in ELISA and Western Blot, and a component of calibration standards.
• Biochemical Research: Employed as a stabilizer for enzymes and other labile proteins, and as a model protein in ligand-binding studies and structural biology.
• Pharmaceutical Excipient: Acts as a stabilizer and bulking agent in the formulation of certain therapeutic proteins, vaccines, and diagnostic products.
• Microbiology: Used as a supplement in culture media for fastidious microorganisms.

Quality Control

Our Albumin, Bovine is manufactured 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 research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity (by electrophoresis), pH, moisture content, endotoxin levels, and biological testing is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. The product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture.
