BSA, AUS Origin, 10kg

A research-grade bulk preparation of Australian-origin bovine serum albumin (BSA) supplied by STEMCELL Technologies supports laboratories that require extensive documentation and traceability for sensitive biological workflows. Sourced from cattle raised in regions recognized as negligible risk for bovine spongiform encephalopathy (BSE), this 10 kg powder format addresses the needs of core facilities, biorepositories, and contract research organizations running high-volume assays.

The lyophilized Fraction V protein serves as a blocking agent in immunohistochemistry and western blot protocols, a carrier for enzyme stabilization, and a media supplement for serum-free cell culture systems. Each lot is screened for endotoxin, protease activity, and heavy-metal content to minimize interference with enzymatic reactions, immunoassays, and downstream protein characterization steps.

Store the sealed container refrigerated and protected from light in a dry environment; for extended shelf life, keep at room temperature with desiccant to prevent moisture uptake. Reconstitute in phosphate-buffered saline or ultrapure water, and sterile-filter when required for cell-based work.

Typical applications include ELISA coating buffers, cryopreservation media formulations, density gradient centrifugation, protein crystallization trials, and immunohistochemistry blocking solutions. The bulk 10 kg pack supports consistent lot-to-lot reproducibility across long-running studies and large-scale screening campaigns.
