This small package of bovine serum albumin (BSA) is accurately pre-measured and easy to make 1%, 3% or 5% fresh blocking buffer. For labs which put budget their first priority, please see our large pack product. Compared to shorter shelf life in a large bottled package, individually packed BSA bags has a longer storage time of at least 5 years.

Our bulk order of BSA is a high purity, lyophilized “Fraction V” powder. This product has been tested and can be used in western blot, IHC, ICC, protease-sensitive Immunoassays such as RIA, EIA and ICF, protein standard, diluent and enzyme stabilizer , hybridization and selected cell culture applications.

Fresh blocking buffer made of preweighed powder BSA performs better than commercial stock solution.
