Product Specific Information
Description: The AER-37 monoclonal antibody reacts with the FcεRIalpha subunit, an IgE-binding subunit lacking signal-transducing ability. FcεRIalpha is expressed on mast and basophil cells and is upregulated by the presence of IgE. FcεRIalpha forms a tetrameric complex with one beta and two gamma subunits. The beta and gamma subunits possess immunoreceptor tyrosine-based activation motifs (ITAM). The FcεRI complex plays an important role in triggering IgE-mediated allergic reactions.
Applications Reported: The AER-37 (CRA1) antibody has been reported for use in flow cytometric analysis. It has been reported to not block IgE binding.
Applications Tested: The AER-37 (CRA1) antibody has been tested by flow cytometric analysis of peripheral blood cells. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
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.
