General description

Neurofilaments are a type of intermediate filament that serve as major elements of the cytoskeleton supporting the axon cytoplasm. They are the most abundant fibrillar components of the axon, being on average 3-10 times more frequent than axonal microtubules. Neurofilaments (10nm in dia.) are built from three intertwined protofibrils which are themselves composed of two tetrameric protofilament complexs of monomeric proteins. The neurofilament triplet proteins (68/70, 160, and 200 kDa) occur in both the central and peripheral nervous system and are usually neuron specific. The 68/70 kDa NF-L protein can self-assemble into a filamentous structure, however the 160 kDa NF-M and 200 kDa NF-H proteins require the presence of the 68/70 kDa NF-L protein to co-assemble. Neuromas, ganglioneuromas, gangliogliomas, ganglioneuroblastomas and neuroblastomas stain positively for neurofilaments. Although typically restricted to neurons, neurofilaments have been detected in paragangliomas and adrenal and extra-adrenal pheochromocytomas. Carcinoids, neuroendocrine carcinomas of the skin, and oat cell carcinomas of the lung also express neurofilaments.

Immunogen

Recombinant fusion protein containing the last 168 amino acids of rat NF-M. Purified from E. Coli inclusion bodies by ion exchange chromatography on DEAE-cellulose in 6 M urea.

Legal Information

CHEMICON is a registered trademark of Merck KGaA, Darmstadt, Germany

Physical form

Affinity purified antibody in PBS, 50% glycerol, and 5 mM sodium azide

Specificity

Reacts with an epitope dependent on the last 84 amino acids of rat NF-M (145K). Reacts specifically with NF-M from a variety of mammalian and avian species. The antibody is not sensitive to the phosphorylation state of the neurofilament.
