R144.4. Homozygous sterile or near-sterile 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 ok2435 homozygotes (grotty, Unc, with vulval blip). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: AACGTATTCCGAAGTGCGAC. External right primer: CCATGAAGAAACCCAGGAAA. Internal left primer: TCAGAAAGATTGTTCCGGTTTT. Internal right primer: GGGGGATTGACGGACTATTT. Internal WT amplicon: 3053 bp. Deletion size: 1544 bp. Deletion left flank: AAATAAGACGGTAAAGAATTTTATCAGAAT. Deletion right flank: TCAGTTCCAAGCTCAAAACCGACTCCACCT.
