Protein G Background

Protein G is an immunoglobulin-binding protein expressed in group C and G Streptococcal bacteria much like Protein A but with differing specificities. It is a 65-kDa (G148 protein G) and a 58 kDa (C40 protein G) cell surface protein that has found application in purifying antibodies through its binding to the Fc region. The native molecule also binds albumin, however, because serum albumin is a major contaminant of antibody sources, the albumin binding site has been removed from this recombinant form of Protein G.

Recombinant Protein G, His Tag (BLI verified)
Utilized protein as a model protein for conjugation development. I am working on developing in-house cysteine conjugation methods and analytics, so this biologically relevant protein bearing a single free cysteine residue was what I was looking for as commercially available single cysteine proteins are hard to come by. The protein served worked well in Ellman's assays and HPLC to establish maleimide conjugation efficiency. Happy with the speed/quality, and the CofA was detailed in how to reconsitute and store the product.
