The present invention provides cells having more than two drug resistance genes and at least two different resistance genes that have been recombined into the chromosome of a cell. It also teaches the processes for preparing cells by recombining two or more different drug resistance genes into the chromosome of a cell. The invention further shows a screening method using the cells of described herein that may be used to accomplish high throughput screening of, among other things, natural products and/or whole cells isolated from the environment.
本发明提供了具有两个以上药物抗性
基因和至少两个不同抗性
基因的细胞,并将它们重新组合到细胞染色体中的方法。该发明还教授了通过将两个或更多不同的药物抗性
基因重新组合到细胞染色体中来制备细胞的方法。该发明进一步展示了使用所述细胞的筛选方法,可以用于高通量筛选
天然产物和/或从环境中分离出的整个细胞,以实现高通量筛选等目的。
