Beschreibung

General description

Highly purified BSA powder manufactured by a proprietary heat-shock fractionation process, followed by treatment to lower fatty acids and lipids. This albumin contains one of the lowest levels of total lipids, fatty acids and free fatty acids of any commercially available albumin. Endotoxin and IgG levels are also very low to absent. This bovine albumin product may be used for cell culture applications as well as a stabilizing agent and for blocking of nonspecific binding. Purity 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.

Preparation Note

Storage temperature <-10 °C
