title: Local radiolabeling of the 68 kDa neurofilament protein in rat sciatic nerves.
abstract: Rat sciatic nerve segments, 4.5 cm distal to the dorsal root ganglion (DRG), were incubated in vivo with [35S]methionine. Fluorography of 2-D polyacrylamide gels of the nerve proteins demonstrated the labeling of the 68-kDa neurofilament protein, which was identified by immunoblotting. This experimental design excludes the dorsal root ganglion as the source of the radiolabeled neurofilament protein and suggests that this neuron-specific protein may be synthesized in axons.
