Recombinant Protein G, CY5

Protein G is an immunoglobulin binding protein in Streptococci. Protein G binds to the Fc region of antibodies and thereby leaves the Fab region available to still bind antigen. Our recombinant version has been engineered to lack the albumin binding domains and has a 6x histidine tag at its N-terminus.
