VC486 C. elegans hlh-17(ok487) IV/nT1 [qIs51] (IV;V). Show Description
F38C2.2. Homozygous lethal deletion balanced by GFP-marked translocation. Heterozygotes are WT with GFP signal in pharynx, and segregate WT GFP, arrested nT1 aneuploids, and non-GFP ok487 homozygotes (early larval arrest). qIs51 homozygotes inviable. Pick WT GFP and check for correct segregation of progeny to maintain. 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.

XA6400 C. elegans hlh-17(ok487) IV/nT1 [qIs51] (IV;V). Show Description
Heterozygotes are WT and GFP+ in the pharynx. ok487 homozygotes arrest as early larvae and are GFP-. qIs51 homozygotes are inviable.
DCR1337 C. elegans nsIs105 I; cima-1(wy84) IV; wyIs45 X; olaEx805. Show Description
nsIs105 [hlh-17p::GFP] I. wyIs45 [ttx-3p::GFP::rab-3 + unc-122p::RFP] X. olaEx805 [hlh-17p::caspase12 + hlh-17p::caspase17 + ttx-3p::mCherry + glr-3p::mCherry + unc-122p::GFP]. Maintain by picking animals with GFP expression in coelomocytes. Ablation of CEPsh glia partially suppresses AIY presynaptic maintenance defects in cima-1(wy84) mutants. nsIs105 (hlh-17::GFP) expression labels CEPsh glia. Reference: Shao Z, et al.
