A snRNA:U6:96Ac ( U6:3 ) promoter drives expression of a dual-gRNA in which a Drosophila tRNA-Gly (G) is followed by a gRNA targeting EGFP, and a second tRNA-Gly (G) is followed by a gRNA targeting GFP. The (F+E) gRNA scaffold described in FBrf0241409 is used.
A snRNA:U6:96Ac promoter drives expression of two sgRNAs (CAACTACAAGACCCGCGCCG and GGTTGTCTGGTAAAAGGACA), each of which target GFP for knockout. The sgRNAs are expressed as a polycistronic cassette based on the tRNA-gRNA design of FBrf0233589.
