Watanabe S, Sakurai T, Nakamura S, Miyoshi K, Sato M (2018) The combinational use of CRISPR/Cas9 and targeted toxin technology enables efficient isolation of bi-allelic knockout non-human mammalian clones. Int J Mol Sci 19:E1075. doi: 10.3390/ijms19041075
Objective: Most genome editing systems employ transient treatment with selective drugs such as puromycin to obtain the desired genome-edited cells, which often allows some untransfected cells to survive and decreases the efficiency of generating genome-edited cells. The authors developed a novel targeted toxin-based drug-free selection system for the enrichment of genome-edited cells.
Summary: Results indicate that a combination of the CRISPR/Cas9 system and targeted toxin technology using IB4-SAP allows efficient enrichment of genome-edited clones, particularly bi-allelic KO clones.
Usage: Cells were trypsinized 3 days after transfection and approximately 80% were incubated for 30 min at 37°C in a solution (25 mcL) containing 0.5–1.0 mcg IB4-SAP (Cat. #IT-10).
