Isolement axoplasme du nerf sciatique du rat

Overview

This article presents a detailed protocol for isolating axoplasm from the adult rat sciatic nerve. The method involves dissection of nerve fascicles and incubation in a hypotonic medium to effectively release myelin and lyse non-axonal structures, leading to the extraction of axon-enriched material.
