Extended Data Fig. 6 |. High resolution view of FIB-SEM section shown in Fig. 5d.
30 nm-thick sections were cut with a gallium ion beam at 30 keV and 770 pA. Images were taken with the electron beam at 2 keV, 0.8 nA, 2 μm working distance, 20 μs dwell time, 6144×4096 pixel frame size. Pixel size 9.7 nm. Scale bar, 10 μm. Full genotype in Supplementary Table 1.
