Rotavirus and Adenovirus Antigen

Explain ：

【TEST PRINCIPLE】
Adeno/Rota Combo Test is a sandwich solid phase immunochromatographic assay. To perform the test, an aliquot of diluted stool sample is added to the sample well of the test
card. The sample flows through a pad containing antibodies against adenovirus and rotavirus coupled to red-colored colloidal gold. If the sample contains adenovirus or rotavirus antigens, the antigen will bind to the antibody coated on the colloidal gold particles to form antigen-antibody-gold complexes. These complexes move on the nitrocellulose membrane by capillary action toward the test line area on which adenovirus and rotavirus specific antibodies are immobilized separately. As the complexes reach the test line, they will bind to the antibody corresponding to the virus on the membrane to form of a line. A red control line will always appear in the result window to indicate that the test has been correctly performed and the test device functions properly. If virus is not present or lower than the detection limit of the test, only the control line will be visible. If the control line dose not developed, the test is invalid
