Additional Information
Statement
Reference

ScerGAL4GSGB12-6 drives mifepristone-inducible expression primarily neuronally. Strong expression is observed in the ventral nerve cord in 4-6 dorsal midline cells per hemisegment; this includes A1-7 dorsal motor neurons. Ventral nerve cord expression is also observed in 20+ lateral cells and 20+ ventral cells per hemisegment. Strong expression is observed in cells throughout the brain region, in chordotonal organs, and at type Is and Ib boutons of neuromuscular junctions of most muscles. Expression is observed in the ring gland. Little detectable uninduced expression is observed in salivary glands and occasional CNS cells.
