125I-labeled DNA polymerases of avian myeloblastosis virus and spleen necrosis virus were used in a radioimmunological characterization of avian retrovirus DNA polymerases. It was shown that avian leukosis virus and reticuloendotheliosis virus DNA polymerases do not cross-react in radioimmunoassays. Within the avian leukosis virus species, species-specific and type-specific antigenic determinants of the DNA polymerase were defined. The previous finding of genus-specific antigenic determinants in avian myeloblastosis virus and Amherst pheasant virus DNA polymerases was confirmed and extended to members of all subgroups of avian leukosis virus. It was shown that there is little immunological variation between the DNA polymerases of the four members of the reticuloendotheliosis virus species. Particles with RNA-dependent DNA polymerase activity from the allantoic fluid of normal chicken eggs and from the medium of a goose cell culture did not compete for the antibodies directed against any of the sets of antigenic determinants defined in this study.
用125I标记的禽成髓细胞瘤病毒和脾坏死病毒的DNA聚合酶对禽逆转录病毒DNA聚合酶进行放射免疫特性分析。结果表明,禽白血病病毒和网状内皮组织增生症病毒的DNA聚合酶在放射免疫测定中不发生交叉反应。在禽白血病病毒种内,确定了DNA聚合酶的种特异性和型特异性抗原决定簇。先前在禽成髓细胞瘤病毒和阿默斯特雉鸡病毒DNA聚合酶中发现的属特异性抗原决定簇得到证实,并扩展到禽白血病病毒所有亚群的成员。结果表明,网状内皮组织增生症病毒种的四个成员的DNA聚合酶之间几乎没有免疫差异。来自正常鸡蛋尿囊液和鹅细胞培养液中的具有依赖RNA的DNA聚合酶活性的颗粒,不与针对本研究中所确定的任何一组抗原决定簇的抗体发生竞争。
