Bovine Serum Albumin (BSA)

Standard grade and reagent grade BSA products from SeraCare offer IVD manufacturers a consistent, reliable source of material for immunoassay, protein-chemistry, and cell culture applications. Useful as blockers, diluents, stabilizers, and protein standards, BSA products serve as crucial components in many industry-leading diagnostic assays.

  • IgG-free, and virtually free of contaminating enzymes, salts, heavy metals, and low molecular weight contaminants
  • Outstanding solubility, with excellent clarity, filterability, and low UV background, even at high concentrations
  • Very low in endotoxin, with low bioburden, and highly soluble in media - important characteristics for veterinary and biotechnology applications


Standard grade BSA

Standard grade BSA product is derived from bovine plasma collected at USDA‑licensed facilities in the United States. Animals received ante‑mortem and post‑mortem inspection under veterinary supervision and were passed as free of infectious or contagious diseases and injurious parasites.

Reagent grade BSA
Reagent grade BSA is collected under the same guidelines as standard grade BSA; however, this product undergoes further processing to produce a highly purified powder. Processing may include extensive membrane dialysis and filtration (including charcoal filtration), helping to minimize analytes, including non‑esterified fatty acids that can cause background interference in sensitive in vitro diagnostic assays, as well as inhibition in sensitive cell and microbial culture systems. Purity levels in reagent grade BSA meet or exceed 98%.

For research use only. Not for use in diagnostic procedures.
