(A-C) Max projections over all images slices (epithelium + AMPs) from wing discs with FLAG tag inserted at the N-terminus of Ths (Bl. 77476). Single image slice of the disc proper (DP) notum (D-F) or underlying AMPs (G-I), corresponding to the region within the yellow dashed box in A. (J-L) Close up of AMPs within the dashed yellow box in G. In all images, FLAG is visualized with anti-FLAG antibody (red), and AMPs are visualized with anti-Cut antibody (cyan). Anti-Cut antibody imperfectly stains AMPs, due to the use of saponin to optimize the visualization of anti-FLAG staining. Note the puncta stained by anti-FLAG antibody within the AMPs. Microscopy scale bars = 100 μm in A-I, and 10 μm in J-L.
