BSA, NZ Origin, 10kg

Research laboratories that require large quantities of low-endotoxin protein for cell culture and immunoassay workflows can rely on this 10 kg lyophilized Bovine Serum Albumin (BSA) from STEMCELL Technologies. The New Zealand Origin designation reflects controlled sourcing standards, making the material appropriate for sensitive applications including stem cell culture, expansion media, and defined media formulations.

In research settings, this grade of BSA is incorporated into western blot and immunohistochemistry blocking buffers, used to prepare standard curves and diluent solutions in ELISA workflows, and added to PCR master mixes as a stabilizer to improve enzyme performance. It also functions as a carrier protein for antibody storage and conjugation, and as an additive in chromatography protocols for protein purification. The powder dissolves readily in aqueous buffers and supports serum-free formulations.

For long-term integrity, the product should be kept dry and protected from light in a cool, sealed environment; reconstituted aliquots may be refrigerated for repeated use. A typical working concentration ranges from 0.1 to 5 % (w/v) depending on the application, and the package is supplied as a single-use bulk powder for reconstitution. Researchers in cell biology, immunology, and molecular biology select this origin for assays where batch-to-batch consistency and low endotoxin contamination are critical to reproducible results.
