Additional Information
Statement
Reference

ScerGAL4GSG2295 drives primarily neuronal mifepristone-inducible expression. Weak expression is observed in ~3-8 ventral and/or lateral cells/hemisegment in the ventral nerve cord, and in a few scattered cells in the brain. Moderate expression is observed in the optic lobes. Strong expression is observed in class III and IV dendritic arborizing neurons (md-da). Variable expression is observed in occasional chordotonal organs. Expression is also observed in the gut. Weak uninduced expression is observed in a subset of CNS cells.
