产品说明
一般描述
Monoclonal Anti-Human IgE (mouse IgG2b isotype) is derived from the GE-1 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from a mouse immunized with purified human IgE myeloma protein. IgE (Immunoglobulin E) is the least abundant immunoglobulin isotype. IgE is produced by plasma cells and is highly functional in the lung, skin, and mucous membranes. Normal levels of IgE in serum are less than 1 μmL.
特异性
Monoclonal Anti-Human IgE specifically recognizes Human IgE. The antibody shows no cross-reactivity with human IgG1, IgG2, IgG3, IgG4, IgA, and IgM.
免疫原
Purified human IgE
应用
Anti-Human IgE-Peroxidase antibody has been used in enzyme linked immunosorbent assay (ELISA).
生化/生理作用
IgE plays a critical role in allergic reactions and host protection from parasites. During an allergic reaction such as atopic eczema, extrinsic asthma or hay fever, fungal and parasitic infection, atopic disease, or primary immunodeficiency the serum IgE levels can be induced up to 5-fold. IgE specifically and reversibly binds to the membrane receptor Fc-epsilon receptors (FcεR) type I on the surface of basophils, eosinophils, and mast cells. This binding activates the release of histamine, leukotrienes, and other mediators responsible for hypersensitivity. The recognition and isolation of allergen-specific IgE can lead to progress in understanding of pathophysiologic mechanisms underlying IgE-associated allergic disorders.
