Abstract

The invention provides a test strip for screening specific cereal allergens IgE. The test strip is coated with a cereal antigen marked by colloidal gold. The test strip utilizes a colloidal gold marking technology; firstly, colloidal gold is used for marking specific cereal allergens; then the marked allergens are uniformly sprayed on a cellulose acetate membrane or a nitrocellulose membrane to prepare the test strip product for allergen detection. The test strip is simple and convenient to operate, accurate in result and low in cost and can realize multi-term free detection.

Description

technical field [0001] The invention relates to the technical field of colloidal gold labeling, in particular to a test strip for IgE screening of specific cereal allergens and a preparation method thereof. Background technique [0002] Allergic disease is the most common disease in contemporary society. It is caused by widespread allergens. About 5-10% of the population in my country and 5-25% of the population in the United States and Europe have suffered from allergic infestation. Among them, young children And teenagers are particularly obvious, and harm is more serious. Allergic reaction (allergy) is a pathological immune response that causes physiological dysfunction and tissue damage when the immune body is exposed to the same allergen again. Involves various clinical departments, such as internal medicine including bronchial asthma, anaphylactic shock, serum sickness, connective tissue disease, glomerulonephritis, migraine, etc., surgery including transplant rejectio...
