Helicobacter Pylori Antigen Quantitative Kit (Fluorescent Immunochromatography Assay of Rare Earth Nanocrystals)（HP Ag）

【Testing purpose】
Helicobacterpylori (HP) is a gram-negative bacterium with strong survival ability and can survive in the strongly acidic environment of the stomach. The presence of HP may put dogs/cats at risk for diarrhea.
Therefore, reliable and effective detection has a positive guiding role in prevention, diagnosis and treatment.

【Detection principle】
This product uses fluorescence immunochromatography to quantitatively detect HP content in dog/cat feces. The basic principle is that the nitrocellulose membrane is marked with T and C lines, 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 antibody in the sample binds to the nanomaterial labeled antibody b to form a complex, which then binds to the T-line antibody A to form a sandwich structure. When the excitation light is irradiated, the nanomaterial emits fluorescent signals. The intensity of the signal was positively correlated with the antigen concentration in the sample.
