syIs554 [nmr-1p::NLS::cGAL(DBD)::gp41-1-N-intein::let-858 3'UTR + flp-20p::NLS::gp41-1-C-intein::cGAL(AD)::let-858 3'UTR + unc-122p::RFP + 1kb DNA ladder (NEB)]. Split cGAL driver for PVC neuron. syIs300 [15xUAS::(delta)pes-10::GFP::let-858 3'UTR + ttx-3p::RFP + 1kb DNA ladder(NEB)] is a GFP cGAL effector.  Some worms do not express ttx-3p::RFP marker, but will consistently produce worms with the transgenic marker in next generation.
