BSA, AUS Origin, 1kg

Bovine Serum Albumin (BSA) sourced from Australian cattle is a high-purity protein commonly used as a blocking agent, carrier protein, and stabilizing component across biomedical research workflows. The Australian origin matters because Australia maintains a documented BSE-free (Bovine Spongiform Encephalopathy) cattle population, making this material a preferred option for laboratories with strict prion contamination control requirements.

Supplied as a 1 kg lyophilized powder, this reagent integrates into ELISA assays, Western blot membrane blocking, immunohistochemistry staining protocols, protein purification chromatography steps, and cell culture media supplementation. Common laboratory applications include preparation of serum-free media, formulation of antibody dilution buffers, stabilization of dilute protein solutions, and reduction of nonspecific binding in immunoassays.

STEMCELL Technologies provides this BSA with full traceability from Australian source herds. For long-term stability, the lyophilized powder should be kept dry and protected from light; reconstituted stock solutions benefit from aliquoting and frozen storage at -20 degrees C to limit freeze-thaw degradation of the albumin structure.
