This strain is homozygous for a deletion (gk840) in F41G4.1, detectable by PCR using the following primers. External left primer: TCGTTCTTTCGTAAAACCCG. External right primer: TTCTGGCTTAAGCTGCCAAT. Internal left primer: GAAGGCAAATTGCTCAGCTC. Internal right primer: TTCAATGTGATCGTCTTCGC. Internal WT amplicon: 1889 bp. Deletion size: 925 bp. Deletion left flank: TGCAGTGTAGAGTCGGGTCAAAAAGACAAG. Deletion right flank: AAGATCAACTACACCAGTCCAATTTTCAAT. Insertion Sequence: ATCAACAAA. Validation: No CGH probes for gk840. Other deletions (gk3131, gk3132, gk3133) identified by CGH. 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.
