FceR1 alpha Monoclonal Antibody (9E1), Invitrogen™

Description

For FACS analysis, use 10 μL of the suggested working dilution to label 1x10^6 cells in 100 μL. Mouse anti Human Fc epsilon R1 alpha antibody, clone 9E1 recognizes the human high affinity Fc receptor for IgE (Fc epsilon R1), which plays a central role in the IgE-mediated allergic response.

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.
