title: [Biochemical characteristics of a calf leukemia virus in chronically infected cells].
abstract: Studied were the conditions of cultivation of FLK cells chronically infected with a calf leucosis virus. The gradient values of density were compared to those of the murine sarcoma virus--1.14--1.15 vs, 1.17--1.18/cm3. Established were the parameters of the reverse transcriptase reaction for the calf leukosis virus (Magnesium-dependent reverse transcriptase). Data showed that the calf leucosis virus may not resolutely be referred either to the B- or the the C-type of retroviruses.
