Depositor Comments

This plasmid has been used with locus-specific CRISPR/Cas9 in a two-step editing process to add a mEGFP tag to the C-terminus of human MYL7 in WTC human induced pluripotent stem cells by the Allen Institute for Cell Science. After initial HDR, stable expression of CAGGS-driven mCherry will indicate cells with integrated donor sequence. This selection cassette is designed to be removed with subsequent CRISPR/Cas9-mediated excision as previously described (https://doi.org/10.1101/342881) A linker of 3-21 amino acids will be produced after excision. To enrich for edited cells, see our protocol for fluorsecence-assisted cell sorting and subcloning of hiPSCs (https://www.allencell.org/instructional-videos-and-tutorials-for-cell-methods.html) Further, we recommend PCR-based assays for identifying precisely edited clones as previously described (https://www.molbiolcell.org/doi/abs/10.1091/mbc.e17-03-0209)
