title: [Properties of a new, oncornavirus D-associated antigen].
abstract: Continuous cells of human origin, HEp-2, and mouse L929 cells taken 24 hours after infection with oncornavirus D were labeled for protein with a mixture of 14C-amino acids and 3H-glucosamine. Specific sera obtained from rabbits were used for testing the virus-specific new antigen in cell extracts and for immunoprecipitation of the new antigen. Electrophoresis in polyacryl amide gel showed the virusspecific new antigen, common for human HEp-2 cells and for oncornavirus-D-infected mouse L929 cells, to be a glycoprotein with a molecular weight of 98,000--100,000 daltons. By its molecular weight it differs from oncornavirus envelope glycoprotein whose molecular weight is 60,000--70,000 daltons. No similar protein was found in noninfected L929 cells.
