HCC27 C. elegans hwSi8 II; unc-119(ed9) III. Show Description
hwSi8 [pie-1p::GFP::mex-3(601-1248)::pie-1 3'UTR + unc-119(+)] II. Worms are healthiest at 15C. Shift to 25C overnight to increase brightness of GFP. Mos1-mediated single-copy insertion (MosSCI) into EG4322. GFP-tagged transgene expressing a portion of MEX-3(601-1248) required for protein degradation. At about the 12-cell stage, soma-germline asymmetry is briefly visible before GFP::MEX-3(601-1248) becomes undetectable even in the germline blastomeres. Detected weakly on P granules only in the presence of endogenous MEX. Reference: Huang NN & Hunter CP. Gene. 2015 Jan 10;554(2):160-73.
HMZ245 C. elegans ccar-1(sda11) IV. Show Description
Superficially wild-type except for a slightly shorter body length in adults. Crispr/Cas9 was used to create a 13 bp deletion in exon7 of ccar-1a; breakpoints: CTGATTCGGGAG/sda11/ATCGGAAGTTTC. sda11 is an isoform-specific deletion allele. It only affects the function of CCAR-1A and CCAR-1D, but not CCAR-1B and C. In addition, because CCAR-1D is not expressed in embryos,this allele can be used to specifically inactivate CCAR-1A (the full-length isoform that is the most similar to human CCAR1) during embryogenesis.

Do not distribute this strain; other labs should request it directly from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
