Comparable to AlbuMAX®, this serum-replacement grade BSA is a highly purified, lyophilized powder. Formulated to optimize the product’s lipid profile for growth promotion, this lipid-enriched BSA is processed to provide a minimum of 98% albumin and to be essentially free of IgG. This low-endotoxin preparation is intended for serum-free and serum-reduced cell culture applications. A supplementation rate ranging from 0.5 to 2.5 mg/mL has been effective in the production of recombinant proteins, virus particles and monoclonal antibodies in cultured cells.
