Additional Information
Statement
Reference

ScerGAL4GSG3669-2 drives mifepristone-inducible expression primarily in neurons. Moderate expression is observed in dorsal midline, ventral midline, lateral, and ventral cells of the ventral nerve cord. Weak expression is observed in a variable subset of chordotonal organs. Occasional expression is observed in ventral multidendritic neurons (v'md). Weak variable expression is observed at the neuromuscular junctions of muscles 1, 2, 3, 4, 6, and 7. Expression is observed in the ring gland and in oenocytes.
