Lactic dehydrogenase virus was grown in primary mouse embryo cells and labeled with (3)H-uridine and (3)H-amino acids. Concentrated and purified virus was banded by isopycnic centrifugation in sucrose gradients, and infectivity and radioactivity were found to correspond at a density of 1.17 g/cm(3). The extracted viral RNA was resolved by electrophoresis in polyacrylamide-agarose mixed gels, and the mol wt was estimated to be 6.0 x 10(6).
乳酸脱氢酶病毒在原代小鼠胚胎细胞中培养,并用³H-尿苷和³H-氨基酸进行标记。浓缩和纯化后的病毒通过在蔗糖梯度中进行等密度离心进行分带,发现在密度为1.17 g/cm³时,感染性和放射性相对应。提取的病毒RNA在聚丙烯酰胺-琼脂糖混合凝胶中通过电泳进行分离,其分子量估计为6.0×10⁶。
