Background
Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin "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. IgE also plays a pivotal role in responses to allergens, such as: anaphylactic reactions to drugs, bee stings, and antigen preparations used in desensitization immunotherapy.

ELISA
Linearity
The concentrations of Mouse IgE were measured and interpolated from the target standard curves and corrected for sample dilution.
The sample is undiluted samples are as follows: C57 Mouse Serum was 40fold dilution. The interpolated dilution factor corrected values are plotted. The mean target concentration was determined to be 319.95 ng/mL in C57 Mouse Serum.
Linearity
The sample is undiluted samples are as follows:C57 Mouse Plasma was 40fold dilution. The interpolated dilution factor corrected values are plotted. The mean target concentration was determined to be 343.92 ng/mL in C57 Mouse Plasma.
To assess the linearity of the assay, three samples were spiked with high concentrations of Mouse IgE in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
