Additional Information

Statement

Reference

ScerGAL4^Tk.PS drives expression in NPF positive adult enteroendocrine cells as well as cells in the brain and thoracico-abdominal ganglion, a subset of which are also positive for NPF.

(Ameku et al., 2018)

ScerGAL4^Tkg.PS drives expression only in Tachykin-secreting enteroendocrine cells in the midgut, and not in Tachykinin-secreting neurons in the brain.
