X-Gal activity staining of leg imaginal discs expressing E. coli and Drosophila genes encoding β-galactosidase driven under the control of dpp-Gal4. dpp-Gal4 is specific to the anterior/posterior compartment boundary. Staining was performed at 25°C in Fe/NaP buffer with or without fixation. While no-UAS control showed no signal, both E-coli lacZ and Drosophila DmelGal showed specific staining both with and without fixation. Scale bar: 100 μm.
