They are similar, however the Serum Replacement Grade BSA that my company provides is specifically for use in serum-free and serum reduced cell culture applications. This BSA is highly a purified, lyophilized powder. It is formulated to optimize the products 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. A supplementation rate ranging from .5 to 2.5 mg/mL has been effective in the production of of recombinant proteins, virus particles and monoclonal antibodies in cultured cells.
Try a free sample to see if out serum replacement grade BSA will help you with your serum free cell culture.
