Additional Information
Statement
Reference

ScerGAL4GSG12-1 drives mifepristone-inducible expression primarily in neurons. It is weakly expressed in 1 cell/hemisegment at the ventral midline of the ventral cord, as well as in a few scattered ventral cells. Moderate expression with variable penetrance is driven in class III and IV dendritic arborizing neurons (md-da neurons), and occasionally in abdominal dorsal bipolar neuron dbp (dbd).
