Example tomogram of a mouse dorsal root ganglion (DRG) axon from dataset 1. Tomogram was used for survey of microtubules and components in axons. Tomogram contains site at which microtubules and endoplasmic reticulum are linked by tethers.

Manual blot for 3 s before plunging.

Adult DRG neurons from GFP-RFP LC3 mouse were grown for 4 days in vitro before vitrification. Tilt series was collected in a thin region of an axon.

61 images per tilt series with 120.2 e/A2 total dose. A zero-centered tilt scheme from minus 30 to plus 60 degrees then minus 30 to minus 60 degrees was used for acquisition.

Frame alignment and dose-filtering was done with alignframes and newstack (IMOD) operated via subTOM. Tilt series alignment and tomogram reconstruction was performed in IMOD.
