The R68A06 enhancer fragment drives expression of the GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain).
The GMR25C08 enhancer fragment followed by the Drosophila synthetic core promoter (DSCP) is fused upstream of the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain).
ScerGAL4DBD.R68A06 expression when combined with HsapRELAAD.R25C08 is stochastic in descending neuron of the posterior brain DNp01.
Labelling of descending neuron of the posterior brain DNp01 is stochastic.
