Protocol for the isolation and culture of mouse dorsal root ganglion neurons for imaging applications.

Sensory neurons play pervasive roles throughout biology. In vitro studies to probe their functions hinge on the successful application of primary cell culture. Here, we present a protocol for the isolation and culture of mouse dorsal root ganglion neurons for imaging applications. We describe steps for extracting dorsal root ganglia, preparing cultures, maintaining them for days in vitro, and performing immunocytochemical labeling. We also include special considerations with respect to additional downstream applications. For complete details on the use and execution of this protocol, please refer to Smith et al. (2021).1.
