The specific method used to test this material for protease activity is considered proprietary. However, it is based on the enzymatic cleavage of FITC-Casein. See the link below to review the FITC-Casein Enzymatic Assay to demonstrate the principle of this method.

Is Product A3059, Albumin from bovine serum (BSA), suitable for use in ELISA?
1 answer-
We have not tested A3059 for specific use in ELISA. However, A3059 is considered to be essentially gamma-globulin free, which makes this more potentially useful in ELISA, by reducing a potential source of background.

Is Product A3059, Albumin from bovine serum (BSA), suitable for use as a blocking agent in immunoblotting?
1 answer-
We have not tested A3059 for specific use in immunoblotting as a blocking agent, in quality control. However, A3059 is considered to be essentially gamma-globulin free, which makes this more potentially useful in blotting experiments, by reducing a potential source of background. The Technical Bulletin states that "Globulin free albumins are suitable for use in applications where no other proteins should be present".
