  • Product nameAnti-200kDa + 160kDa Neurofilament antibody [SMI-33]
    See all 200kDa + 160kDa Neurofilament primary antibodies
  • Description
    Mouse monoclonal [SMI-33] to 200kDa + 160kDa Neurofilament
  • SpecificityAb24569 reacts with a nonphosphorylated epitope accessible in both, phosphorylated and nonphosphorylated neurofilament H and, to a lesser extent, in neurofilament M. In contrast to other antinonphosphoneurofilaments, reaction with isolated normal neurofilaments is not intensified by dephosphorylation.

Application Abreviews Notes
  • Application notesELISA: 1/1000.
    ICC: Use at an assay dependent dilution. Post-fixation in cold methanol or methanol/hydrogen peroxide is recommended.
    IHC-P: 1/1000 (on tissues fixed with paraformaldehyde or formaldehyde-containing fixatives such as Bouin). Perform heat mediated antigen retrieval before commencing with IHC staining protocol (autoclaving deparaffinized sections for 10 min in distilled water or by boiling unembedded 0.5 cm thick blocks in Tris buffered saline, pH 9.0, in a microwave oven for 15 min).
    IHC-Fo: 1/1000. Use at an assay dependent dilution (on tissues perfusion fixed with paraformaldehyde or formaldehyde-containing fixatives such as Bouin). Post-fixation in cold methanol or methanol/hydrogen peroxide is recommended.
    Reaction is poor in material fixed in glutaraldehyde / paraformaldehyde, and in material treated with trypsin.

    WB: 1/1000. Predicted molecular weight: 160-200 kDa.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • RelevanceNeurofilaments usually contain three intermediate filament proteins: L, M (160kDa), and H (200kDa) which are involved in the maintenance of neuronal caliber. 200kDa Neurofilament has an important function in mature axons that is not subserved by the two smaller Neurofilament proteins. There are a number of repeats of the tripeptide K S P, 200kDa Neurofilament is phosphorylated on a number of the serines in this motif. It is thought that phosphorylation of 200kDa Neurofilament 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 (NFM and NFH), the levels of phosphorylation being altered developmentally and coincident with a change in the neurofilament function.
