Transgene in which the Avic\GFPE.3xP3 marker present in M{vas-Cas9.S} has been inactivated using a gRNA that targets EGFP. The resulting M{vas-Cas9.S.GFP-} transgene is marked only with Disc\RFP3xP3.PB.
vas regulatory sequences drive expression of human codon-optimized Cas9 endonuclease tagged with the Tag:NLS(SV40-largeT) nuclear localization signal.
