      Reference

      ScerGAL4GMR20B01 drives expression in interneurons in the embryonic/larval central nervous system. Labeling is seen in a subset of neurons in the first instar larval brain and very few neurons of the ventral nerve cord. The number of labelled neurons in the abdominal neuromeres is increased in wandering third instar larva but expression in the brain is no longer observed at this stage.
