A dot blot hybridistion test for bovine rotavirus is described using non-radioactive digoxigenin labeled VP4 eDNA probe. The sensitivity of the probe was compared with that of RNA polyacrylamide gel electrophoresis. The detection limit for rotavims RNA in a sample by VP4 eDNA probe was 37.5 times higher than RNA-PAGE. VP4 eDNA probe could detect as little as 2 ng of viral RNA and was highly specific also.
