Abstract

The invention relates to an immunoassay detection kit, and provides an allergenic specific IgE antibody immunoassay detection kit and a preparation method thereof. The detection kit comprises magnetic microspheres coupled with allergenic protein, magnetic microspheres coupled with anti-human IgE antibody, a human IgE antibody standard substance, alkali phosphatase labeled anti-human IgE antibody and an alkali phosphatase chemical luminous substrate AMPPD. The preparation method for the detection kit comprises the following steps: coupling the allergenic protein to the magnetic microspheres, coupling the anti-human IgE antibody to the magnetic microspheres, preparing the human IgE antibody standard substance, preparing the alkali phosphatase labeled anti-human IgE antibody, preparing the alkali phosphatase chemical luminous substrate AMPPD and packing the combination. The detection kit has the advantages of high sensitivity, high accuracy, quick response, convenient usage, low dosage and low cost, can assist in precisely and quantitatively measuring sensitive allergene, and guides clinical anaphylactic reaction treatment.

Description

technical field [0001] The invention relates to an immunoassay detection kit, in particular to an allergen-specific IgE antibody immunoassay detection kit and a preparation method thereof. Background technique [0002] Anaphylaxis detection is an important prerequisite for the treatment of anaphylaxis. Specific IgE antibodies in the patient's serum can be detected to determine what allergen is sensitizing the patient and the degree of sensitization. [0003] For many years, enzyme-linked immunosorbent assay (ELISA) has been commonly used to detect specific IgE antibodies in serum. The corresponding ELISA detection kit includes a microtiter plate coated with allergen protein, human IgE standard, enzyme-labeled antibody and substrate chromogenic solution. The content of specific IgE antibodies in serum is very low, and it is difficult for ELISA detection kits to provide high enough sensitivity, especially for the detection of small or trace amounts of specific IgE antibodies,...
