hpIs636 [rig-3p::HisCl1::SL2::mCherry]. hpEx4479 [npr-4p::snb-1::pHluorin + lin-15(+)]. Pick animals with green fluorescence in VNC to maintain. Synapse exocytosis marker in AVA. Transgenic animals exhibit punctate green fluorescent signals along AVA neurites in the ventral cord, with stronger expression than in a wild-type background. mCherry and HisCl1 expression in AVA soma and neurites. In the presence of histamine, the SNB-1::pHluorin intensity will decrease in neurites.

hpIs636 [rig-3p::HisCl1::SL2::mCherry]. mCherry expression in AVA soma and neurites along VNC. Non-specific mCherry expression in gut. HisCl activation leads to reduced forward and reversal activity.
