ProA/G^TM is prepared by covalently coupling recombinant Protein
(contains five Ig-binding regions of protein A and three Ig-binding regions of protein G)
to 4% cross-linked agarose beads.
Protein A/G binds to all human IgG subclasses and also binds to IgA, IgE, IgM and to a lesser
extent IgD;  therefore, it has a broader species binding range than either Protein A or Protein G.
Unlike non-recombinant Protein G, Protein A/G does not bind serum albumin
because the gene sequence coding for the albumin binding site has been removed.
Protein A/G is an excellent tool for purification and detection of mouse monoclonal antibodies
from IgG subclasses because Protein A/G binds all mouse IgG subclasses
but does not bind IgA, IgM or murine serum albumin.
In addition, ProA/G^TM displays high chemical and physical stability as well as high flow rate,

hydrophilicity and high gel strength.
It can be used for IgG purification and immunoprecipitation.​
