A general method for constructing and selecting recombinant vaccinia viruses with insertions, deletions, or mutations in any gene that is similar in principle to one originally devised for Saccharomyces cerevisiae (S. Scherer and R. W. Davis, Proc. Natl. Acad. Sci. USA 76:4951-4955, 1979) is described. The selectable marker used, Escherichia coli guanine phosphoribosyltransferase, is not retained within the final recombinant virus, and hence, this procedure may be used serially to introduce several foreign genes or to make multiple site-directed mutations.
本文描述了一种构建和筛选重组痘苗病毒的通用方法,该方法可用于在任何基因中进行插入、缺失或突变,其原理与最初为酿酒酵母设计的方法类似(S. 谢勒和R. W. 戴维斯,《美国国家科学院院刊》76:4951 - 4955, 1979)。所使用的选择标记是大肠杆菌鸟嘌呤磷酸核糖转移酶,它不会保留在最终的重组病毒中,因此,该程序可连续用于引入多个外源基因或进行多个位点定向突变。
