Release of Particle Associated RNA Dependent DNA Polymerases by Primary Chicken and Quail Embryo Cells
Recently a new RNA dependent DNA polymerase has been described [1,2]. This enzyme is enclosed in sedimentable structures — “particles” —, and can be prepared from the allantoic fluid of embryonated virus free chicken eggs. The “particles” and the purified polymerase are different from the known avian RNA tumor viruses [1,2,3]. In this report we describe the appearance of this enzyme in the culture medium of primary chicken and quail embryo cells.
