F38B7.1. Homozygous viable deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok2506 homozygotes (Unc, mostly sterile with vulval blip, but some animals reproduce). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TTCATCTCACCGGAAGGAAC. External right primer: AACTTGGATGAAACGTTGGC. Internal left primer: AGCACCACCACCAAAGAATC. Internal right primer: AGCTATTGCGATTGCGGTAA. Internal WT amplicon: 2935 bp. Deletion size: 973 bp. Deletion left flank: GTCACAGTATCATAATGTCACAATGAAGCA. Deletion right flank: TTTCCCAATCAAATCTCTTCATTATTTTAT. Insertion Sequence: A. 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.
