Monoclonal Anti-IgE-FITC antibody produced in mouse

Immunoglobulin E (IgE) is encoded by the gene mapped to human chromosome 14q32.33. IgE belongs to the immunoglobulin family and consists of epsilon(ε) heavy chain in the constant (C) region. IgE has a monomeric structure with an extra domain in the constant region.

The antibody BE5 reacts with human IgE; it recognizes an epitope different from the ones recognized by 4G7 and 4H10 antibodies to IgE.

Purified human IgE

The reagent is designed for Flow Cytometry analysis. Suggested working dilution is 5 μg/mL of sample. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.

Immunoglobulin E (IgE) binds very tightly to Fc receptors on basophils and mast cells. Thus, it plays a major role in stimulating allergic reactions. Elevated expression of the gene has been associated with the development of hyper IgE Syndrome (HIES), hay fever, atopic skin diseases such as eczema, anaphylactic shock and IgE-myeloma. In addition, overexpression of IgE is also observed in allergy/asthma. Therefore, increased levels of serum IgE can be considered as a diagnosis for asthma. IgE expression is down-regulated in congenital agammaglobulinemia and hypogammaglobulinemia because of faulty metabolism or synthesis of immunoglobulins.
