otis445 [ace-2p::RFP + LacO repeats]. gwIs39 [baf-1p::GFP::lacI::let-858 3'UTR + vit-5p::GFP]. RFP expression in cholinergic motor neurons. LACI::GFP aggregates on LacO repeats to form two dots in every nucleus. vit-5::GFP is expressed in intestine at L4 stage and later. Reference: Patel T & Hobert O. eLife 2017.

otIs545 [gcy-5p::RFP + LacO repeats]. otIs593 [let-858p::GFP::LacI + ttx-3p::mCherry]. Maintain at 20C; otIs545 is very unstable at lower temperatures. RFP expression in ASER neuron. LACI::GFP aggregates on LacO repeats to form two dots in every nucleus. otIs545 is unstable, presumably due to the highly repetitive nature of the LacO array. Stock should be periodically examined for RFP expression and GFP localization to retain expression of the array. Reference: Patel T & Hobert O. eLife 2017.

ccEx7271 [let-858::GFP + pha-1(+)]. This strain expresses nuclear-localized GFP in all somatic nuclei, but reduced or no GFP in germ cells. If maintained at 20C, pha-1(ts) genotype will select for transgenic animals. Sporadic germ cell expression can be observed when maintained at 25C.

dcr-1 homozygotes are completely sterile. qIs48 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and a gut promoter driving GFP in the intestine, and is homozygous lethal. Segregates WT glowing hets, non-glowing steriles , very rare homozygous hT2 glowing animals, and dead eggs. 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. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.
