General description

A high purity, low endotoxin and low IgG BSA powder preparation with near native albumin characteristics. This BSA is first isolated by a proprietary heat-shock/ organic solvent process and further purified by non solvent based methodologies to reduce endotoxins to very low levels resulting in a highly monomeric bovine albumin that retains many of the binding, transfer, and physical properties of native albumin. Purity is = 98%; typical purity is 100%. This BSA may be used for molecular biology applications.
