Human IgE(Immunoglobulin E) Introduction

IgE is a type of antibody (or immunoglobulin (Ig) "isotype") that has been found only in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing four Ig-like constant domains (Cε1–Cε4). IgE is thought to be an important part of the immune response against infection by certain parasitic worms, including Schistosoma mansoni, Trichinella spiralis, and Fasciola hepatica. IgE is also utilized during immune defense against certain protozoan parasites such as Plasmodium falciparum. IgE may have evolved as a defense to protect against venoms. IgE also has an essential role in type I hypersensitivity, which manifests in various allergic diseases, such as allergic asthma, most types of sinusitis, allergic rhinitis, food allergies, and specific types of chronic urticaria and atopic dermatitis. 

Human IgE(Immunoglobulin E) ELISA Kit Test Method

This kit uses sandwich ELISA to detect the concentration of Human IgE.

Human IgE-specific monoclonal antibody has been pre-coated in the wells of the supplied microplate. Standards samples and controls are added to interact with the immobilized antibody. A sandwich complex is formed by additional anti-Human IgE antibody with HRP-Streptavidin. TMB solution is added to react with the sandwich for ming optical signal measured by microplate reader. The concentration of Human IgE in the sample can be calculated by comparing the absorbance of the sample with the standard curve.
