Abstract: FCER1A Products

Background: FcεR1alpha is subunit of the high affinity receptor for IgE to which IgE directly binds. FcεR1 is a tetrameric complex consisting of one alpha, one beta and two γ subunits. The latter two subunits are required for signal transduction activity. The FcεR1 complex plays an important role in triggering allergic responses. The CRA1 (AER37) monoclonal antibody reacts with the FcεR1alpha subunit on a region that does not overlap the region of the IgE binding site, thus it does not compete with IgE for the receptor binding. Since the CRA2 (AER24) monoclonal antibody reacts with the IgE binding site on FcεR1alpha, it competes with IgE for the receptor binding. Combining the two antibodies, one can quantitatively measure the amounts of the IgE-bound FcεR1alpha.
