rtIs29 [acr-5p::YC2.60 + pha-1(+)] expresses yellow cameleon YC2.60 in all VB and DB motoneurons and some head and tail neurons. Maintain at 25C to select for the presence of the array. Haspel G, et al. (2010) J. Neurosci. 30:11151-6.

rtIs11 [osm-10p::GFP + osm-10p::HtnQ150 + dpy-20(+)]. osm-10 promoter drives expression of both GFP and Htn-Q150 strongly in ASH and more weakly in other neurons of the head and tail. pqe-1(rt13) accelerates Htn-Q150 induced toxicity resulting in ASH neuron cell death predominantly during larval stages. Hence, many adult animals will lack overt GFP expression in ASH neurons. rtEx377 in the original HA759 was selected against leaving only rtIs11 in the strain available at the CGC.
