Abstract

The invention relates to a magnetic particle reagent and a kit for chemiluminescence immunodetection. The magnetic particle reagent comprises magnetic particles coated by 0.5-1.5mg/mL streptavidin oranti-fluorescein isothiocyanate antibody, 0.5-5mg/mL protein, 0.5-10mg/mL chloroacetamide type protein protection agent, 1-10mg/mL preservative, 5-10mg/mL polyol compound and 1-5mg/mL buffer solutionof surfactant, wherein the polyol compound is polyol or polysaccharide, and the surfactant is at least one of Brij35, TX-100 and peregal O-20. The magnetic particle reagent can disperse the magnetic particles uniformly and stably for a long time and can maintain activity and stability of streptavidin or anti-fluorescein isothiocyanate antibody and protein in unfavorable environment like high temperature, so that chemiluminescence immunoassay is large in chemiluminescence value, high in repeatability and small in background value.

Description

technical field [0001] The invention relates to a magnetic particle reagent and a kit for chemiluminescence immunoassay, belonging to the technical field of chemiluminescence immunoassay. Background technique [0002] In recent years, there have been a variety of immunoassay methods in the field of immunoassay, among which magnetic particle chemiluminescence immunoassay is a new type of labeled immunoassay technology that combines chemiluminescence system with immune reaction to detect trace antigens or antibodies. It has the advantages of good selectivity, high sensitivity, strong specificity, no radioactive hazard, fast analysis speed, simple equipment, etc. It has been widely used in the fields of environment, clinical, food, drug detection, etc. development trend. [0003] At present, magnetic particle chemiluminescence immunoassay kits have been widely used in the market, but the magnetic particle reagents in the existing kits have poor stability in adverse environment...
