title: [The technology for isolating the avian myeloblastosis virus in high titers from leukosis-free chicks].
abstract: In order to enhance the outcome of high-quality reverse transcriptase enzyme, an efficient biotechnology was developed of accumulating and isolating the avian myeloblastosis virus (AMV) in high titres from blood plasma of leukosis-free chickens. When commercial chickens are infected in most sensitive one-day age, the virus titre does not exceed the value of 10(12) particles per 1 ml of plasma. We used 3-4-day old leukosis free chickens and achieved a stable average titre of the virus of 5.10(12) particles/ml due to adaptation of the virus to such chickens and their selection for a high sensitivity to AMV.
