腮腺炎病毒Enders株和M_(56-1)株的结构蛋白经SDS-PAGE后,用~(125)I分别标记VP1-4,酶解并进行肽图分析,结果两组病毒VP1-4肽图差异明显,表明毒株间编码结构蛋白的基因不同。
The structural proteins of mumps virus Enders and M_ (56-1) strains were digested by SDS-PAGE and labeled with ~ (125) I, VP1-4 was digested and analyzed by peptide mapping. As a result, the two VP1-4 peptides The difference is obvious, indicating that the genes encoding the structural proteins are different between the strains.
