Problems solved by technology

[0003] The limitations of the washing conditions described in the current chemiluminescence immunoassay kits must be equipped with expensive equipment for the experiment, and the experimental operation steps of the current kits are cumbersome. Some chemiluminescence detection kits have low sensitivity and high reagent costs. Currently, they are generally only in the top three It has been carried out in hospitals, but less in hospitals below the top three. Therefore, it is necessary to develop a chemiluminescence kit with high sensitivity, good accuracy and low detection cost.

Abstract

The invention discloses a chemiluminescence detection kit. The kit comprises a reagent 1 and a reagent 2, wherein the reagent 1 is prepared from a buffer solution, magnetic particles, a first antibodyof a biotin-labeled to-be-detected antigen, and polyhydric alcohol; and the reagent 2 is prepared from a buffer solution, a second antibody of an acridinium ester-labeled to-be-detected antigen, andpolyhydroxy saccharide. The chemiluminescence detection kit is high in sensitivity and good in accuracy, and can lower the detection cost.

Description

technical field [0001] The invention relates to the field of in vitro diagnostic reagents, in particular to a chemiluminescence detection kit. Background technique [0002] The chemiluminescence detection kit utilizes two detection substances (antibodies, antigens or other molecules with affinity for specific analytes) to detect a certain substance in the sample. One of the detection substances is coated on the solid surface (hereinafter referred to as solid phase), and the other detection substance is labeled with enzyme or chemiluminescent substance (hereinafter referred to as label). The current analytical method for the use of chemiluminescent immunoassay kits is to use a luminescent agent as a marker of an antibody or antigen, and directly detect the content of the antigen or antibody in the specimen to be tested through a luminescence reaction. The principle steps of the kit are as follows: ①Add the sample to be tested into the reaction cup, keep it warm for a period ...
