[Virion precipitation reaction based on determination of reverse transcriptase activity: Method of study of membrane antigens of oncornaviruses].
A method for the study of the envelope antigens of oncornaviruses of C, B, and D types by the virion precipitation test (VPT) based on the measurement of the amount of precipitated virus by its reverse transcriptase activity is described. The method is immunologically specific for titration of antibody to the envelope antigens of oncornaviruses. By means of the VPT it is possible to identify oncornaviruses, to study antigenic relationships between them and to detect some or other antigens in virion coat.
