Neurofilaments from ox spinal nerves. Isolation, disassembly, reassembly and cross-linking properties.


ABSTRACT: An isolation procedure for neurofilaments from ox spinal nerves is described where the triplet polypeptides (which have molecular weights of 205 000, 158 000 and 72 000) constitute more than 80% of the preparation. Soon after purification, the neurofilaments form a gel that is stable for many weeks. The purified neurofilaments disassemble in low-salt buffers at pH greater than 7.0 into soluble particles that contain all of the triplet polypeptides. Greater than 90% of the protein can reassemble to form filaments. The thiol-containing residues in the filaments can be cross-linked. Analyses of the complexes formed show that in the filament the 205 000-mol.wt. components are arranged to that they can be cross-linked to themselves and to the 158 000-mol.wt. polypeptides, and that the 72 000-mol.wt. components are arranged so that their thiol groups can be cross-linked together.
