Abstract
A method for detecting bi-allelic gene edited cells based on CRISPR/Cas12a technology is provided. The method provides crRNA, a nucleotide sequence of which that binds target is SEQ ID NO: 6. The crRNA is transcribed from a transcription template in vitro; the transcription template is a product obtained by annealing a single stranded DNA molecule shown in SEQ ID NO: 10 and a single stranded DNA molecule shown in SEQ ID NO: 13. The method provides crRNA of CD71 gene and constructs a CRISPR/Cas12a system using the same for CRISPR/Cas12a detection, achieving the screening for CRISPR/Cas9 induced CD71 gene bi-allelic gene edited cells. This method is simple, easy, fast, and cost-effective for screening a large number of mutant cells.
