Novel colloidal gold reagent strip device

Technical Field

The utility model belongs to the technical field of medical supplies detects, especially, relate to a novel colloidal gold reagent strip device.

Background

Colloidal gold immunochromatography is a solid-phase labeled immunoassay technique. The principle is that a sample solution is dripped into a sample pad, a sample to be detected is chromatographed to a gold-labeled pad under the influence of capillary force, a colloidal gold marker in the gold-labeled pad is redissolved in the solution, if a corresponding antibody (or antigen) exists, the colloidal gold marker is specifically combined to form an antigen-antibody-colloidal gold compound, the forward chromatography is continued, when the colloidal gold compound passes through a detection line (T line), the antigen-antibody-colloidal gold compound is subjected to antigen-antibody specific reaction and captured, and an obvious red line appears here, namely the sample is positive; if the sample does not contain the antibody (or antigen) to be detected, the sample crosses the detection line, no antigen-antibody reaction occurs, the antibody (or antigen) coated with the colloidal gold in the gold label pad reaches the quality control line, and only the quality control line (C line) shows a red line, namely negative. The colloidal gold labeling substance can be classified into various methods such as a double antigen (antibody) sandwich method, an indirect method, a competitive method, and a capture method. The existing colloidal gold reagent strip device needs to dilute a detected object in the detection process and then carry out detection, is very inconvenient, and has a complex structure and is easy to cause reagent pollution.
