【Detection principle】 This product uses fluorescence immunochromatography to quantitatively detect the HP content in dog/cat feces. Basic principle: T and C lines are drawn on the nitrocellulose membrane respectively, and the T line is coated with antibody a that specifically recognizes the antigen. The binding pad is sprayed with another fluorescent nanomaterial-labeled antibody b that can specifically recognize the antigen. The antigen in the sample first combines with the nanomaterial-labeled antibody b to form a complex, and then the upward chromatography, the complex and the T-line antibody a Combined to form a sandwich structure, when the excitation light is irradiated, the nanomaterial emits a fluorescent signal, and the strength of the signal is positively correlated with the antigen concentration in the sample.
【Test Purpose】 Helicobacter pylori (HP) is a Gram-negative bacillus with strong survival ability and can survive in the strong acidic environment in the stomach. The presence of HP may put the dog/cat at risk for diarrhea. Therefore, reliable and effective detection plays a positive guiding role in prevention, diagnosis and treatment.
