Abstract

Radioimmunoassays were developed for the 19,000, 15,000, and 12,000 molecular weight polypeptides of avian myeloblastosis virus and for the 19,000 and 12,000 polypeptides of RAV-0, a subgroup E avian tumor virus. Each polypeptide was shown to possess both group- and type-specific antigenic determinants, in contrast to the 27,000 mol wt polypeptide, which contained only group-specific determinants. The corresponding low-molecular-weight polypeptides of subgroup A, B, and E viruses were shown to be immunologically indistinguishable. The findings that low-molecular-weight polypeptides of subgroup C and D viruses reacted very differently in immunoassays for the respective polypeptides of avian myeloblastosis virus or RAV-0 suggest that subgroups C and D may have evolved differently form subgroups A, B, and E.

摘要

已针对禽成髓细胞瘤病毒分子量为19000、15000和12000的多肽以及E亚群禽肿瘤病毒RAV-0的分子量为19000和12000的多肽开发了放射免疫测定法。与仅含有群特异性决定簇的27000道尔顿多肽相反,每种多肽都显示同时具有群特异性和型特异性抗原决定簇。已证明A、B和E亚群病毒相应的低分子量多肽在免疫上无法区分。C和D亚群病毒的低分子量多肽在针对禽成髓细胞瘤病毒或RAV-0各自多肽的免疫测定中反应差异很大,这一发现表明C和D亚群可能与A、B和E亚群的进化方式不同。
