Protein G

Recombinant Protein G

The gene we selected to use for the production of Protein G originated from Streptococcus Strain G148, and was cloned and expressed in our proprietary strain of Escherichia coli. The regions of the gene corresponding to the albumin binding domains, as well as the cell wall and cell membrane binding domains, have been genetically deleted, however the Fc binding domain is still present. Our recombinant Protein G contains 196 amino acid residues and has a predicted molecular mass of approximately 22.5 kDa, but migrates with an apparent molecular mass of about 30 kDa in SDS-PAGE.

Protein Description

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.
