A simplified agarose gel electrophoresis for rotavirus detection

The use of agarose gel electrophoresis for rotavirus detection is a suitable routine method if simplifying modifications are introduced. Incorporation of ethidium bromide into the agarose gel permits its use for several times in the course of one week without further staining of the RNA segments. The electrophoresis chamber with a UV-light-transparent bottom is put directly onto the transilluminator and the RNA bands of the rotavirus can be visualized without manipulating the gel tray. During the winter of 1990/91, we found a good sensitivity (98%) of this method in comparison to a latex agglutination test (Slidex Rota-Kit 2, bio Mérieux).
