Rapid Testing of CRISPR Nucleases and Guide RNAs in an E. coli Cell-Free Transcription-Translation System
Summary: We present a protocol to rapidly test DNA binding and cleavage activity by CRISPR nucleases using cell-free transcription-translation (TXTL). Nuclease activity is assessed by adding DNA encoding a nuclease, a guide RNA, and a targeted reporter to a TXTL reaction and by measuring the fluores...
