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.
