Product Specific Information
MA1-4997 detects Fc epsilonR1 alpha from human samples. The CRA1 (AER37) monoclonal antibody reacts with the Fc epsilonR1 alpha 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 bindings.
MA1-4997 has been successfully used in Western blot, immunocytochemistry, flow cytometry, and immunohistochemistry (paraffin, frozen) applications.
The MA1-4997 immunogen is region of Fc epsilonR1 alpha which does not overlap with the IgE binding site.
The epitope has been mapped to amino acids 26-110.
Target Information
Fc epsilon RI alpha, also known as FceR1 alpha, is a subunit of the high-affinity receptor for IgE, primarily expressed on mast cells and basophils. Its expression is upregulated by the presence of IgE. Fc epsilon RI alpha forms a tetrameric complex with one beta and two gamma subunits, which are essential for signal transduction. The beta and gamma subunits contain immunoreceptor tyrosine-based activation motifs (ITAMs). The Fc epsilon RI complex plays a crucial role in triggering IgE-mediated allergic reactions. When allergen-bound IgE molecules bring together two or more high-affinity IgE receptors, it leads to the release of mediators such as histamine, which are responsible for allergy symptoms. This process couples allergens and mast cells to initiate inflammatory responses characteristic of allergic disorders like hay fever and asthma. The release of histamine and proteases also leads to the synthesis of prostaglandins and leukotrienes, which are potent effectors of the hypersensitivity response.
