ceh-6(mg60) is lethal. Maintain by picking WT and check that it throws 1/4 Dpys. mg60 is a 1.3 kb deletion that removes part of the conserved POU-specific domain. PCR with primers PCR6-5 GAA-TTC-ATG-AAA-TCG-GAG-GCG-T (->) and PCR6-3 GTG-AGA-AGT-GAA-GAG-GAT-TGT-A (<-) yields a band of about 1.6 kb instead of 280 bp as in N2. Backcrossed more than 10 times; in addition, the left arm of LG I was recombined with lin-28 to remove the mutator locus.

K02B12.1. Homozygous lethal deletion chromosome balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP ok3388 homozygotes (early larval arrest). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TCTCTTTCTTCCAGCTTGCC. External right primer: TAGGGCCAGAAAATTGAACG. Internal left primer: AAATGTAGAATTGGGCGAGC. Internal right primer: GGTAGGCGCACATACCATTT. Internal WT amplicon: 1129 bp. Deletion size: 405 bp. Deletion left flank: TCTGAATAATTTCAGGTCGTTCAACTTCCT. Deletion right flank: AAAATGGTATGTGCGCCTACCAATTGAAAA. Insertion Sequence: AAAAGGATTCA.

otIs458[ceh-63p::GFP + unc-119(+)]. GFP expression in DVC neurons. Can be used to isolate DVC by FACS. Derived by outcrossing parental strain OH11974 to remove him-5(e1490). Used by CeNGEN project for RNA-Seq (https://www.cengen.org/).

syIs530 [ceh-63p::NLS::GAL4(sk)::VP64::let-858 3'UTR + unc-122p::RFP + 1kb DNA ladder (NEB)] cGAL driver for DVC neurons. syIs300 [15xUAS::(delta)pes-10::GFP::let-858 3'UTR + ttx-3p::RFP + 1kb DNA ladder(NEB)] is a GFP cGAL effector.  Some worms do not express ttx-3p::RFP marker, but will consistently produce worms with the transgenic marker in next generation.
