How the assay works
In this assay the IgE present in samples reacts with the anti-IgE antibodies which have been adsorbed to the surface of polystyrene microtiter wells. After the removal of unbound proteins by washing, anti-IgE antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound IgE. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3',5,5'-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of IgE in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of IgE in the test sample. The quantity of IgE in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.

Biological function summary
The IgE protein functions as a mediator in allergic reactions. It does not operate as part of a complex but directly interacts with allergens and the IgE-specific receptors on immune cells. IgE's role is important in defense against parasitic infections where it performs a protective function by promoting eosinophil activation and degranulation. This action helps the body to expel the parasites. In the absence of parasitic infection IgE's function translates into its role in allergic responses where it becomes responsible for the symptoms associated with allergic diseases.
Pathways
IgE is an important player in the immune response pathway. The protein interacts with allergy-related pathways such as the T helper 2 (Th2) pathway. IgE's role in this pathway involves cooperation with cytokines notably IL-4 and IL-13 which are produced by Th2 cells and promote IgE synthesis in B cells. Also IgE is linked to the FcεRI receptor signaling pathway that initiates the release of histamines and other mediators when IgE binds to an allergen leading to an allergic response.
