This fatty acid-free bovine albumin is excellent for in vitro transport and binding studies. It is also suitable in diagnostic systems for blocking non-specific binding sites in ELISA and Western blotting and as a diluent and stabiliser in RIA/ELISA. Produced by heat shock fractionation and subsequent treatment with solvent. This fatty acid-free bovine albumin is excellent for in vitro transport and binding studies.
