[Detection of oncornavirus D-induced antigen in cells by a mixed hemadsorption method]

Further study of a new oncornavirus D-induced antigen was done. Its immunological specificity and localization in cells was determined by a sensitive method of mixed hemadsorption. A continuous HEp-2 cell culture was used as the source of the new as well as virus antigen. Adsorbed specific sera to the new antigen and to oncornavirus D obtained by the previously developed method were used for the antigens detection. This method demonstrated localization of both virus antigens and oncornavirus D-induced antigens not included into the virion structure on the surface of oncornavirus D-infected cells. Mixed hemadsorption test as well as complement-fixation test gave the results identical in their specificity indicating the presence in HEp-2 cells of a new non-virion antigen.
