Protocol to prepare mouse spinal cord for patch-clamp and histology experiments

The spinal cord is a part of the central nervous system located within the spinal canal of the vertebrae. Here, we present a protocol to prepare mouse spinal cord sections for patch-clamp and histology experiments. We describe steps for isolating spinal cord from the spinal canal and obtaining acute slices for patch-clamp experiments. For histology experiments, we detail fixing spinal cord for cryosectioning and imaging. This protocol provides procedures to assess neuronal activity and protein expression of sympathetic preganglionic neurons. For complete details on the use and execution of this protocol, please refer to Ju et al.(1)
