Capitalizing on the inherent multiplexing capability of AsCpf1, we developed a multiplexed, high-throughput screening strategy that minimizes library size without sacrificing gene targeting efficiency. We demonstrated that AsCpf1 can be used for functional genomics screenings and that an AsCpf1-based multiplexed library performs similarly as compared to currently available monocistronic CRISPR/Cas9 libraries, with only one vector required for each gene. We construct the smallest whole-genome CRISPR knock-out library, Mini-human, for the human genome (n = 17,032 constructs targeting 16,977 protein-coding genes), which performs favorably compared to conventional Cas9 libraries.
利用 AsCpf1 的固有多重功能，我们开发了一种多重、高通量筛选策略，在不牺牲基因靶向效率的情况下最小化文库规模。我们证明了 AsCpf1 可用于功能基因组筛选，并且基于 AsCpf1 的多重文库的性能与当前可用的单顺反子 CRISPR/Cas9 文库相当，每个基因仅需要一个载体。我们构建了最小的全基因组 CRISPR 敲除文库 Mini-human，用于人类基因组（针对 16977 个编码蛋白的基因有 17032 个构建物），与传统的 Cas9 文库相比，表现良好。
