Immunoglobulin E (IgE) is a type of antibody that has only been found in mammals. IgE is synthesised by plasma cells. IgE's main function is immunity to parasites. It has an essential role in type I hypersensitivity, 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 drugs, bee stings, and antigen preparations used in desensitization immunotherapy. Sample Type: Serum, plasma, cell culture samples, biological fluids. Intended Use: This ELISA kit is used for in vitro quantitative determination of IgE. Sensitivity: <0.8ng/ml Range: 4-300ng/ml Specificity: Rat, no significant cross-reactivity or interference between this analyte and its analogues was observed. Precision: Intra-Assay: <10% Inter-Assay: <12% Test Principle: This IgE BioAssay? ELISA kit is a sandwich ELISA assay for the quantitative measurement of IgE i
