umnIs52 [myo-2p::mKate2 + NeoR, III: 8856215 (intergenic)] II. Mes. Deletion of 858 bp with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break in parental strain N2. Heterozygotes are wild-type GFP+ mKate2+, and segregate wild-type GFP+ mKate2+ heterozygotes, GFP+ non-mKate2 viable adults that produce progeny most of which are sterile (ve777 homozygotes), sterile Dpy non-GFP mKate2+ (mT1 homozygotes), and dead eggs (aneuploids). Maintain by picking wild-type GFP+ mKate2+ and check for correct segregation of progeny. Left flanking Sequence: TTTTCTTGAGCTTCATCGTCATCGAATCCG ; Right flanking sequence: TGGATTATCCATttttgaactgaaaattca. sgRNA #1: AAAATTATCAGCGAGGGAGA; sgRNA #2: AATAAGTCGATTTCTTTAGA. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.
