CRISPR Cas9 ROSA26 Safe Harbor Targeting System. Since the ROSA26 promoter and exon1 of splice variant 2 were not present in the targeting vector, this finding confirms that the recombinedR26t1Δ gene locus drives iM2 expression from the ROSA26 promoter. The fusion cDNAs were inserted into the ROSA26 genomic locus next to the stop sequences flanked with loxP so that fluorescent proteins were expressed under the ubiqui-tous ROSA26 transcriptional machinery when the loxP sequences were recombined with Cre. The locus is believed to encode three non-coding transcripts of unknown functions. Gad2 Cre/wt (Jackson laboratories stock #010802 24,) and Rosa26 nT-nG/ nT-nG (Jackson Laboratories stock #023537) were crossed to generate Gad2 Cre/wt; Rosa26 nT-nG/wt mice and embryos.
