Recombinant Streptococcus Protein G is produced in E. coli and is a non-glycosylated polypeptide chain containing 196 amino acids. Streptococcus Protein G is proprietarily produced in E. coli and purified via chromatographic techniques. The product obtained is consistent in quality and yield because our proprietary bacterial platform is engineered to be deficient of major proteolytic activities. Protein G binds through a non-immune mechanism specifically to the Fc region of IgG and to all the human subclasses. It also has a strong affinity to monoclonal mouse IgG1 and rat IgG.
