title: [The cytological and immunological characteristics of a virus-producing FLK 44/2 culture].
abstract: Results obtained from cytological and immunological analysis of FLK 44/2 cells indicate the transformation and heterogenization of BLV-producing cell culture. Karyotypic changes of the culture were observed, as well as alterations in its antigenic specificity leading to antigenic diversion. The cell population displayed a high proliferation activity limited by topoinhibition and culture medium exhaustion. An immunocytochemical investigation of virus-producing cell population, using monoclonal and polyclonal antibodies against BLV revealed various cellular forms of BLV-expression. A possibility is discussed to use the immunological approach for selection and establishment of cellular clones exhibiting appropriate virus production parameters.
