F(ab')2 fragment antibodies are generated by pepsin digestion of whole IgG antibodies to remove most of the Fc region while leaving some of the hinge region. F(ab')2 fragments have two antigen-binding Fab portions linked together by disulfide bonds and therefore they are divalent. The average molecular weight is about 110 kDa. They are used for specific applications, such as to avoid binding of secondary antibodies to live cells with Fc receptors or to Protein A or Protein G.Based on immunoelectrophoresis and/or ELISA, the antibody reacts with whole molecule bovine IgG. It also reacts with the light chains of other bovine immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody may cross-react with immunoglobulins from other species.
Works as expected.

It’s easy to use. The results were precise (good reproducibility). I didn’t observe anything strange.
