Description

Description: The MAR-1 monoclonal antibody reacts with the Fc epsilon Receptor I alpha subunit, an IgE-binding subunit lacking signal-transducing ability. Fc epsilon RI alpha is expressed on mast and basophil cells and is up-regulated by the presence of IgE. Fc epsilon RI alpha forms a tetrameric complex with one beta and two gamma subunits. The beta and gamma subunits possess immunoreceptor tyrosine-based activation motifs (ITAM). The Fc epsilon RI complex plays an important role in triggering IgE-mediated allergic reactions. Applications Reported: This MAR-1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This MAR-1 antibody has been tested by flow cytometric analysis of MC/9 cell line (a mouse mast cell line). This can be used at less than or equal to 0.06 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. eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet laser (405 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser. Filtration: 0.2 μm post-manufacturing filtered.

FceR1 (Fc epsilonR1 alpha) is a subunit of the high affinity receptor of IgE. Fc epsilonR1 alpha is a tetrameric complex consisting of one alpha, one β and two additional subunits. The latter two are required for signal transduction activity. The Fc epsilonR1 complex plays an important role in triggering allergic responses, and the immunoglobulin epsilon receptor (IgE receptor) is the initiator of the allergic response. When two or more high-affinity IgE receptors are brought together by allergen-bound IgE molecules, mediators such as histamine, which are responsible for allergy symptoms, are released. The IgE receptor couples allergen and mast cells to initiate the inflammatory responses that are characteristic of disorders such as hay fever and asthma. The release of histamine and proteases leads to the synthesis of prostaglandins and leukotrienes-potent effectors of the hypersensitivity response.
