Y50D7A.4. Apparent homozygous lethal deletion chromosome balanced by dpy-1-marked recombination suppressor. Heterozygotes are WT, and segregate WT, Dpy (sC1 homozygotes), and gk3089 homozygotes (arrest stage/phenotype undetermined). Pick WT and check for correct segregation of progeny to maintain. External left primer: TTTATCCGAATTTTCTGCGG. External right primer: ATTTTCAACGGAATTCGACG. Internal left primer: GAAAATTTTGCATTTTCAAGGC. Internal right primer: TCCGCGATTTTTATAGCATTTT. Internal WT amplicon: 940 bp. Deletion size: 647 bp. Deletion left flank: TTTTGTCAAGCCTCAAATCCCACAATTTTG. Deletion right flank: ATAAATGAGCCAAAATTCGTCAAATTCTGT. Attribution: This strain was provided by the C. elegans Reverse Genetics Core Facility at the University of British Columbia, which is part of the international C. elegans Gene Knockout Consortium, which should be acknowledged in any publications resulting from its use.
