[Comparative analysis of the electrophoretic mobility of the high-molecular virus-specific proteins of flaviviruses].

A comparative study of high molecular virus-specific proteins in cells infected with flaviviruses from 5 serological subgroups was carried out. Proteins NV5, NV4, and V3 were found to have similar electrophoretic mobility in viruses of the tick-borne encephalitis (TBE) complex with the exception of Powassan virus protein. Proteins NV5 and NV4 of mosquito-borne flaviviruses differ in electrophoretic mobility both from the corresponding proteins of the TBE complex viruses and from each other. Protein NV4 1/2 is formed only in cells infected with TBE complex viruses. Varying electrophoretic mobility of protein NV3 in different flaviviruses attests to its virus-specific nature.
