Abstract

The invention discloses a kit for detecting IgG antibodies of allergens of 30 types of foods and a preparation method and relates to the technical field of biomedical in-vitro diagnosis. A linear immunoassay method is adopted, and specific IgG allergens of 30 types of common foods including corns, rice, soybeans, wheat, watermelons, pineapples, oranges, peaches, apples, mangoes, bananas, Hami melons, grapes, strawberries, beef, chicken, egg white/egg yolk, pork, mutton, milk, mushrooms, tomatoes, spinach, green soybeans, cashew nuts, peanuts, sesames, crabs, shrimps and scallops, a quality control line and a critical value line cover a membrane strip, which is prepared on a nitrocellulose membrane, in parallel; the sensitivity (a signal value) is high and the stability is high; the IgG antibodies of the allergens of 30 types of the common foods in human blood serum can be detected and tedious operation of independently detecting antibodies related to an Elisa method methodological kit one by one is overcome, so that the detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of biomedical in vitro diagnosis, in particular to a kit and a preparation method for detecting 30 food allergen IgG antibodies. Background technique [0002] At present, common food allergens in clinical laboratory samples are generally detected by enzyme-linked immunosorbent assay (Elisa). [0003] This method is to coat allergens in 96 microwell plates, incubate and react clinical samples, and finally interpret the results with a microplate reader. This method can usually detect 14 food allergen IgG at one time, and one experiment can only The detection of a single indicator has low throughput and high detection cost, which has limitations in expanding the allergen detection project. Contents of the invention [0004] The purpose of the present invention is to provide a kit and preparation method for detecting 30 food allergen IgG antibodies, thereby solving the aforementioned problems in the prior art...
