title: A rapid detection of avian oncovirus group-specific antigens in feather pulp by the enzyme-linked immunosorbent assay.
abstract: An ELISA procedure for the detection of avian sarcoma-leukosis gs antigen in feather pulp of adult birds is described. The test can be used for identifying gs+ and gs- chickens in leukosis-free populations. The titres of exogenous and endogenous virus-coded gs antigens overlap and the ELISA can be used only for a preliminary screening of unknown chicken populations.
