Description: The mA-6E1 monoclonal antibody reacts with the heavy chain of mouse IgA. It does not react with other isotypes of antibody, including IgD, IgG or IgM, or with other species isotypes. IgA, which is mainly found as a dimer through association of the J chain, is found in mucous secretions, but not in plasma. Fluorochrome conjugated mA-6E1 is used as a detection secondary for mouse IgA primary antibodies.
