Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Protein A/G is a genetically engineered protein containing 5 IgG-binding regions of protein A and 2 of protein G. Cell wall binding region, cell membrane binding region and albumin binding region have been removed from the Protein A/G to ensure the maximum specific IgG binding. Protein A/G is ideal for purification of polyclonal or monoclonal IgG antibodies. It binds to various human, mouse and rat IgG subclasses and to total IgG from cow, goat, sheep, house, rabbit, guinea pig, pig, dog and cat.

Recombinant Protein A/G binds to various human, mouse and rat IgG subclasses (e.g. human IgG1, IgG2, IgG3, IgG4; mouse IgG2a, IgG2b, IgG3; rat IgG2a, IgG2c) and to total IgG from cow, goat, sheep, house, rabbit, guinea pig, pig, dog and cat.
