title: Antigenic determinants specific to the envelope glycoprotein of exogenous avian tumor viruses.
abstract: Antibody in the sera of 15B X 7(2) chickens was measured for reactivity to determinants of the envelope glycoprotein of endogenous and exogenous avian tumor viruses. The pattern of reactivity of animals infected with exogenous sarcoma virus served to operationally define a class of determinants present on the envelope glycoprotein of exogenous viruses and absent from that of the endogenous virus Rous-associated virus-0.
