Specificity Statement:This antibody is specific for murine IgE. It does not react with other classes of mouse immunoglobulin including IgD, IgG, IgA, or IgM. IgE plays an essential role in type I hypersensitivity (allergic responses such as hay fever, asthma, hives, anaphylatic shock) by binding to Fc receptors on basophils and mast cells. Crosslinking of IgE bound to Fc receptors induces degranulation of mast cells and basophils that promote allergic manifestations. IgE is also functionally important for immunity against parasites.
Application Notes:In the original study, this antibody and other clones (C12B9, 23G3, and B1E3) of the monoclonal anti-mIgE antibodies were used in conjunction with the recombinant chimeric mIgE-human IgG1 molecules (Keegan et al., 1991). It has been demonstrated that the Cϵ3 domain is important in the binding of mIgE to the murine B cell FcϵRII as well as to the murine mast cell FcϵRI (Keegan et al., 1991). Also, while the Cϵ4 domain had no effect on binding to the FcϵRI, the presence of the Cϵ4 domain influenced the binding of the recombinant IgE to the FcϵRII (Keegan et al., 1991). This antibody blocks IgE binding to mouse or rat FceRI and can be used in mouse IgE ELISA. In addition, this antibody could be used, for instance, to develop a flow cytometry assay for the identification and differentiation of chemicals with the potential to elicit irritation, IgE-mediated, or T cell-mediated hypersensitivity responses (Manetz et al, 1999), or to study the kinetics of the ligand-IgE interaction (Posner et al., 1992).
