Description: This goat antibody reacts with the Fc fragment of heavy chains on human IgG but notwith the light chains on most human immunoglobulins. No antibody was detected against human IgM or IgA, or against nonimmunoglobulinserum proteins. This antibody has been tested to ensure minimalcross-reaction with bovine, horse, and mouse serum proteins, but the antibody may cross-react with immunoglobulins fromother species.
