中文摘要：

定向进化方法作为新兴的高效蛋白质工程手段，其内容包括蛋白质突变体文库的构建和有效突变体的快速筛选。高通量筛选方法是定向进化方法的重要组成部分，是成功获得有效突变体的关键。筛选的突变体数量越多，获得有效突变体的几率越大。以下介绍了目前已经成功应用于或有潜力应用于定向进化改造蛋白质的几种高通量筛选工具。高通量筛选工具的不断设计与开发将推动蛋白质工程领域的技术革新。

英文摘要：

As an efficient and promising protein engineering strategy, directed evolution includes the construction of mutant libraries and screening of desirable mutants. A rapid and high-throughput screening method has played a critical role in the successful application of directed evolution strategy. We reviewed several high-throughput screening tools which have great potential to be applied in directed evolution. The development of powerful high-throughput screening tools will make great contributions to the advancement of protein engineering.
