Recombinant protein G is produced in a strain of E. coli which contains the gene for protein G from Streptococcus sp. It is supplied as a salt-free lyophilized powder.
Recombinant protein G binds to the Fc region of many types of immunoglobulin G including:
• all four subclasses of human IgG • mouse IgG • rabbit IgG • guinea pig IgG • rat IgG • goat IgG • sheep IgG • cow IgG • horse IgG
Recombinant protein G does not bind to IgG from chicken or cat, or to human IgA, IgM, or serum albumin. It binds weakly to IgG from dog.
