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.
本文描述了一种通过病毒体沉淀试验（VPT）研究C型、B型和D型肿瘤病毒包膜抗原的方法，该试验基于通过逆转录酶活性测量沉淀病毒的量。该方法在免疫方面具有特异性，可用于滴定针对肿瘤病毒包膜抗原的抗体。借助VPT，可以鉴定肿瘤病毒，研究它们之间的抗原关系，并检测病毒体衣壳中的某些抗原。
