Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning
Cytoskeleton, EarlyView.ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...
