Abstract

The invention discloses a kit and a method for detecting the allergen-specific IgE antibody of cat hair. The kit comprises a calibration product, a quality control product, a biotin-labeled cat hair allergen solution, an alkaline phosphatase labeled mouse anti-human IgE secondary antibody solution and streptavidin labeled nano magnetic micro particle suspension; the kit is used for detecting the allergen-specific IgE antibody of cat hair. By the mode above, each reagent component in the kit is good in stability, and the period of validity can be more than or equal to one year; the detection flexibility is high, the specificity is good, and variation is tiny. A perfect uniform technology is obtained via the technological optimization of a great amount of experiments, and production is carried out according to the standardized production operation instructions and quality control instructions vigorously. A user can perform standard operation according to the operation specification so as to obtain the reliable result. In the clinical study, the conforming relevance to imported reagents abroad is higher than or equal to 90%, and the expense is only 1/2 that of the imported reagents abroad.

Description

technical field [0001] The invention belongs to the field of biological immune in vitro diagnosis of medical equipment, in particular to a kit and method for cat hair allergen-specific IgE antibodies. Background technique [0002] Type I allergic diseases mediated by IgE antibodies are quite common. The total incidence of allergic diseases in countries around the world is about 15%-30%. In my country, about 5-10% of people are harassed by allergens. It is the current worldwide It is listed by the World Health Organization (WHO) as one of the three major diseases that should be prevented and controlled in the 21st century. [0003] Allergic diseases are triggered by the body's B cells to produce specific immunoglobulin E (ImmunoglobulinE, IgE) after the patient inhales, ingests, or injects substances containing allergens (called allergens or allergens, IgE), thereby triggering Allergic reaction (or allergy, Allergy) diseases and related symptoms, such as allergic asthma, hay ...
