General description

Anti-Human IgE antibody, Mouse monoclonal (mouse IgG2b isotype) is derived from the GE-1 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with purified human IgE myeloma protein. Immunoglobulin E (IgE) is the least abundant immunoglobulin isotype in circulation. IgE is produced by plasma cells and is highly functional in the lung, skin and mucus membranes. Normal levels of IgE in serum are less than 1 μg/ml.

purified human IgE myeloma protein

Application

Anti-Human IgE antibody, Mouse monoclonal has been used in various immunological techniques, including enzyme linked immunosorbent assay (ELISA), immunoblot, immunoprecipitation and IgE quantification using piezoelectric (Pz) crystal bioassay.

Biochem/physiol Actions

Immunoglobulin E (IgE) plays a critical role in allergic reactions and host protection from parasites. Serum IgE levels are highly elevated during an allergic reaction (such as atopic eczema, extrinsic asthma or hay fever, fungal and parasitic infection, atopic disease or primary immunodeficiency). Detection and measurement of total IgE concentrations is crucial for diagnosis, monitoring and treatment of allergy patients. In addition, the recognition and isolation of allergen-specific IgE can lead to progress in understanding of pathophysiologic mechanisms underlying IgE-associated allergic disorders.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

The best-known function of immunoglobulin E (IgE) is the initiation of allergic reaction. However, it does not make sense that IgE exists only for allergy, which is harmful for the body and does not have a beneficial role. In this
