Description

Technical Field

[0001] The utility model relates to the technical field of reagent detection, and particularly to a household POCT molecular colloidal gold detection device. Background Art

[0002] Colloidal gold is a commonly used labeling technology. It is an immunolabeling technology that uses colloidal gold as a tracer marker for antigens and antibodies. It has its unique advantages. The basic principle is: use colloidal gold to label an antigen or antibody, and coat the corresponding paired antigen or antibody on the NC membrane of the reagent. When the sample contains the corresponding specific antibody or antigen, the colloidal gold labeled particles combine with the ligand in the sample to form a complex, which is then chromatographed on the NC membrane and then coated with the antigen or antibody to form a visible detection (T) line. The result is determined by the presence or absence of the detection line. It has the advantages of simple operation, rapid response, high sensitivity, strong specificity, suitable for on-site detection, and economical and practical.

[0003] Home POCT molecular colloidal gold detection devices are mainly used for molecular detection of poultry and aquatic animals. The existing detection process requires the samples to be individually mixed and diluted in the laboratory for testing, which is a complicated process and high cost. Utility Model Content
