ot835 [gcy-5::SL2::mNeonGreen] III. otTi6 [hsp16-41p::che-1::2xFLAG] X. otTi6 is a miniMOS insertion of heatshock inducible che-1. Under normal growth conditions, very dim expression of gcy-5 is observed in the ASER and RIGL/R neurons. Upon heatshock, induction of CHE-1 leads to ectopic expression of gcy-5 (ectopic expression varies depending upon age at heatshock and genetic background).
