Evaluation of CRISPR activity of human iPS cells by NEPA21 transfection

NEPA21 ips

  1. Optimization of transfection conditions using the NEPA21 super electroporator (Nepa Gene Co., Ltd.) in human iPS cell lines. Voltage and pulse width of Poring Pulse were examined. EGFP expression plasmids were transfected and the percentage of positive cells was analyzed using the LSRFortessa Cell Analyzer (BD).
  2. Schematic of transfection procedure.
  3. Cas9 expression vector pHL-EF1a-SphcCas9-iP-A (Addgene ID: 60599) and sgRNA expression vector pHL-H1-ccdB-mEF1a-RiH (Addgene ID: 60601) were electroporated into iPS cells and then the endogenous dystrophin gene cleavage activity was evaluated by the T7EI assay. The intensity of the cleaved bands (◀ red arrows) was detected with a TapeStation (Agilent) and the values are shown below the gel electrogram images.
  4. The same genomic DNA samples as in (C) were analyzed by RFLP with restriction enzyme XcmI (50-CCANNNNN^NNNTGG-30). The intensity of the uncut bands is indicated by ◀ red arrows. Because gRNA5 cleaves far from the XcmI site, no cleavage activity was detected in the RFLP assay.
