The recombinant protein A protein G fusion protein (r-PAG) fused 8 antibody Fc binding regions, including 5 Fc binding domains of Staphylococcus aureus protein A and 3 Fc binding domains of Streptococcus protein G, with the removal of the cell wall binding domain, albumin binding domain, and non-specific binding domain in protein A and protein G.
Compared with protein A or protein G alone, it has a broader binding range, can bind to all human IgG subtypes, IgA, IgE, and IgM, but cannot bind to mouse IgA, IgM and serum albumin, and is suitable for the extraction and detection of mouse IgG monoclonal antibody. At the same time the fused r-PAG reduces the dependence on pH, allowing binding at pH5-8.
