[Properties of new antigens and viral antigens of transplantable cultures of human malignant cells].
Physico-chemical and immunological differences between a new virus-associated antigen of human cell cultures and the antigen of oncornavirus D persisting in them were established and shown to facilitate their detection and differentiation. The activity of the new antigen is lost or decreases considerably after treatment with ether or chloroform but is retained after heating at 60 degrees C. The viral antigen is relatively stable to ether and chloroform but is inactivated at a temperature of 60 degrees C. The peculiar physicochemical properties of the new and virus antigens may be used for search of approaches for preparation of monospecific virus antisera containing no antibody for the new antigen of cells in human tissue cultures.
