Albumin from bovine serum, powder, IgG-free, cell culture tested by Merck
Prepared by salt fractionation, ion exchange, and gel filtration chromatography. Bovine serum albumin (BSA) makes up approximately 50% of the total protein in serum. Although it may be used as a carrier for hapten immunization in animals other than goats and sheep, it is more commonly used as a carrier for hapten in immunoassays. The small size of BSA, its abundance in serum, and the similarity between BSA and albumins from other species makes it less desirable for antibody production.
