Giardia Antigen Test Kit (GIA Ag)

This product is a fluorescent immunochromatographic method for the quantitative analysis of GIA in dog/cat feces. Basic principle: T and C lines are drawn on the nitrocellulose membrane, the T line is encapsulated with antibody a which specifically recognizes the antigen, and another antibody b labeled with fluorescent nanomaterials which specifically recognizes the antigen is sprayed on the binding pad, the antigen in the sample firstly combines with the antibody b labeled with nanomaterials to form a complex, and then chromatography is carried out upward, and this complex binds with the antibody a on the T line to form a sandwich structure, when the excitation light is irradiated, the nanomaterials emit fluorescent signals, and the strength of this signal correlates with the concentration of the antigen in the sample. When the excitation light is irradiated, the nanomaterial emits a fluorescent signal, and the strength of the signal is positively correlated with the concentration of antigen in the sample.
