HOW IS THIS PROTEIN PRODUCED AND WHAT IS THE REST 2% IMPURITY? THANKS!
1 answer-
This product is prepared by an ammonium sulfate precipitation process followed by a heat treatment and ion exchange chromatography purification. The specific details are considered proprietary. There is no treatment or handling during production that would be expected to cause deglycosylation of the protein. The residual impurities have not been identified. This product is tested for endotoxin and iron. Please see the Sample Certificates of Analysis: https://www.sigmaaldrich.com/certificates/Graphics/COfAInfo/fluka/pdf/PDF746107.pdf
