      DescriptionAnti-Neurofilament H (200 kDa) Antibody, lysine-serine-proline repeat
      Background InformationNeurofilaments 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. For more neurofilament information see Nervous System Cell Type Specific Marker chart online under the CHEMICON Technical Support section.

      Applications
      ApplicationDetect Neurofilament H (200 kDa) using this Anti-Neurofilament H (200 kDa) Antibody, lysine-serine-proline repeat validated for use in IH(P), WB, IH.
      Key Applications
      • Immunohistochemistry (Paraffin)
      • Western Blotting
      • Immunohistochemistry
      Application NotesImmunohistochemistry: 1:250-1:1,000 AB1991 is not affected by the level of neurofilament phosphorylation and is particularly good for revealing dendritic and perikaryal neurofilaments.

      Biological Information
      ImmunogenE. Coli recombinant fusion protein containing 37 lysine-serine-proline repeats of rat NF-H.
      Epitopelysine-serine-proline repeat
      HostRabbit
      SpecificityStrong reactivity to the major neurofilament subunit HF-H. Since a second neurofilament subunit, NF-M, also contains a few lysine-serine-proline (KSP) sequences, there is generally some reactivity with this protein also. AB1991 stains both phosphorylated and dephosphorylated neurofilaments.

      UniProt SummaryFUNCTION: SwissProt: P12036 # Neurofilaments usually contain three intermediate filament proteins: L, M, and H which are involved in the maintenance of neuronal caliber. NF-H has an important function in mature axons that is not subserved by the two smaller NF proteins.
      SIZE: 1026 amino acids; 112480 Da
      PTM: There are a number of repeats of the tripeptide K-S-P, NFH is phosphorylated on a number of the serines in this motif. It is thought that phosphorylation of NFH results in the formation of interfilament cross bridges that are important in the maintenance of axonal caliber. & Phosphorylation seems to play a major role in the functioning of the larger neurofilament polypeptides (NF-M and NF-H), the levels of phosphorylation being altered developmentally and coincident with a change in the neurofilament function.
      DISEASE: SwissProt: P12036 # Defects in NEFH are a cause of susceptibility to amyotrophic lateral sclerosis (ALS) [MIM:105400]. ALS is a neurodegenerative disorder affecting upper and lower motor neurons, and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology is likely to be multifactorial, involving both genetic and environmental factors.
      SIMILARITY: SwissProt: P12036 ## Belongs to the intermediate filament family.
