Description

General description

This BSA powder is manufactured by a proprietary heat-shock fractionation process, using caprylic acid as an albumin stabilizer. A highly consistent and widely used grade of BSA powder for a wide spectrum of immunoassays, cell culture and microbial fermentation applications. This BSA is low in sodium and chloride as well as highly monomeric. Purity specification is >= 98%; typical purity is 100%.

Application

Probumin^® BSA products are fit for use as blockers, protein/antibody (conjugate) stabilizers, and in immunoassays (EIA, RIA and serology systems).

Features and Benefits

• High-quality and reliability. Assurance of consistency in performance and supply.
• Proprietary heat shock and cold solvent fractionation process optimizes the protein yield, purity, and efficacy of BSA. Large batch capacity.
• Safe serum sourcing from USDA-licensed facilities exclusively from U.S. cattle.
• Standard product.
• Wide range of utility.
