Total cell lysates (15 µg protein) from HeLa and HEL were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with purified HRP anti-human FcεRIα Antibody (clone AER-37). Proteins were visualized with chemiluminescence detection. Tubulin-γ antibody was used as a loading control.

High affinity IgE receptor (FcεRI) plays a key role in IgE-mediated allergic immune response. FcεRI is a tetrameric receptor complex, which is composed of one α-subunit (FcεRIα), one β-subunit, and two γ-subunits. FcεRIα directly binds IgE with high affinity, while the β- and γ-chains are responsible for mediating intracellular signals. FcεRIα is a 50 kD transmembrane protein with Ig superfamily structure. It is primarily found on mast cells and basophils. Further studies have indicated that FcεRIα is also expressed on many inflammatory cells including cutaneuos Langerhans cells, dendritic cells, monocytes of patients with allergic disorders, platelets, bronchial epithelial cells, eosinophils produced in hypereosinophilic syndrome, and neutrophils from allergy-induced asthma patients.

- Recommended Usage
-
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested dilution is 1:1000-1:4000. The optimal dilution should be determined by titration for each individual assay of interest.
25 µl and 100 µl of Direct-Blot™ HRP antibody can be used for approximately 5 and 20 Western blots, respectively, at the recommended concentration/dilution. - Application Notes
-
Clone AER-37 (CRA-1) has been reported to bind the receptor even in the presence of IgE.4
