Problems solved by technology

[0005] In addition, the activation of basophils and its detection process are affected by many factors, such as the serum collection process (choice of anticoagulant), whole blood or isolated white blood cells, whether to add IL-3 and its concentration, allergens (concentration and time), erythrocyte lysate (type) (Pan Qingjun et al., J Immunoassay Immunochem.35:368-377,2014; Pichler WJ(ed):Drug Hypersensitivity.Basel,Karger,2007,391-402), selection of identification parameters , the setting of the activation threshold (the degree of change of the activation index), etc. These factors may affect the judgment of the activation result, and then the diagnosis of clinical diseases

Abstract

The invention provides a kit for detecting basophil activation and a using method of the kit. The kit comprises a scrubbing solution, an irritant reference substance, fluorescently-labeled basophil recognition antibodies, red blood cell lysis buffer and an antibody staining solution, wherein the fluorescently-labeled basophil recognition antibodies comprise the following basophil recognition antibodies: Anti human CD 11b, Anti human CD 123, Anti human CD 203c and Anti human CD 63; different basophil recognition antibodies have different fluorescent markers. After the kit is used for detecting the basophil activation situation, the known influence factors of the basophil activation and detection can be avoided, the basophil activation situation can be comprehensively and accurately identified and detected, and a better service is provided for the detection of the basophil activation in the aspect of clinical application and scientific research.

Description

technical field [0001] The invention relates to a detection kit for basophil activation and a use method thereof, in particular to a flow cytometry detection kit for basophil activation and a use method thereof. Background technique [0002] At present, the incidence of allergic diseases is increasing year by year in the world. Especially in developing countries, allergic diseases caused by environmental pollution and food hygiene have gradually attracted everyone's attention. Such diseases occupy medical resources The ratio increased month-on-month and significantly affected the quality of life of patients. [0003] Basophils have been known for more than 130 years and are the main effector cells of allergic diseases (Pan Qingjun et al., Chinese Journal of Immunology, 2009, 23(1):25-28). Studies have found that activation is a key step for basophils to exert their biological functions. The study of its activation mechanism has also developed from the classic IgE-mediated a...
