Serological and electrophoretic typing of red clover mottle virus isolates

Serological and immunoelectrophoretic properties of 22 RCMV isolates from Czechoslovakia were determined. Based on the differences among the isolates, two electrophoretic types were established: type I--isolates with one non-separable electrophoretic form, and type II--isolates with two electrophoretic forms. Depending on the mobility of the electrophoretic forms these types could be subdivided further into two subtypes each. In all selected isolates representing the individual electrophoretic types and subtypes two isoelectric points were determined at pH 5.2 and pH 5.6.
