Description

Technical Field

[0001] The utility model belongs to the technical field of reagent detection, and specifically relates to a reagent card incubation device and an immunochromatographic analyzer. Background Art

[0002] Immunochromatography is a unique immunoassay method. It often uses strip-shaped fiber chromatography materials as solid phase. Through capillary action, the sample solution migrates on the chromatography strip, and at the same time, the analyte in the sample reacts with the receptor (such as antibody or antigen) on the chromatography material with high specificity and high affinity. During the chromatography process, the immune complex is enriched or retained in a certain area (detection zone) of the chromatography material. Through enzyme reaction or direct use of visually observable markers (such as colloidal gold), intuitive experimental phenomena (such as color development) are obtained, while the free marker crosses the detection zone to achieve the purpose of automatic separation from the bound marker. This analytical technology is simple and fast to operate, and the analysis results are clear and easy to judge.
