WebNov 15, 2024 · In this study, an insect cell/baculovirus expression system was used for simultaneous detection of multiple genotypes (SAV1, SAV2, and SAV5) and an indirect double-antibody sandwich-enzyme linked immunosorbent assay (IDAS-ELISA) method was adopted, based on the highly conserved region (E1) of SAV1-6. WebBovine rotavirus (BRV) is one of main pathogens responsible for diarrhea, fever, and vomiting. In this study, we developed a colloidal gold immunochromatographic test strip for detecting BRV according to the principle of double-antibody sandwich. The monoclonal antibodies (mAbs) and polyclonal antibodies (pAbs) were prepared and purified.
