  • FunctionNeurofilaments 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.
  • Involvement in diseaseDefects 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.
  • Sequence similaritiesBelongs to the intermediate filament family.
  • Post-translational
    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.
    Phosphorylated in the Head and Rod regions by the PKC kinase PKN1, leading to inhibit polymerization.

Anti-Neurofilament heavy polypeptide antibody [NF-01] images

  • Immunohistochemical analysis of paraffin-embedded human cerebellum tissue sections labelling Neurofilament heavy polypeptide protein with ab7795 at 5 µL.

  • ab7795 at a dilution of 1/1000, staining Neurofilament heavy polypeptide (Alexa 488 secondary at 1/2000) in rat brain tissue (30µm thick coronal sections) on free floating IHC (see protocol link for detailed description). Image taken with a 40x objective. No labeling observed following omission of primary antibody.

    Sections were viewed using an Axioplan 2 Imaging microscope (Imaging Associates) fitted with 10x, 20x and 40x Plan-Neofluorobjectives (Zeiss, Germany) and images were taken using a AxioCam Hrm digital camera (Zeiss, Germany) and AxioVision software (Imaging Associates).

  • Overlay histogram showing SH-SY5Y cells stained with ab7795 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab7795, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was a goat anti-mouse DyLight® 488  (IgG; H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Thank you for your inquiry.

I can confirm that we do not have ab73273 in our catalog anymore.

I can suggest ab7795 as alternative. It also recognizes a phosphorylated epitope on heavy neurofilament protein (210 kDa) of various speci...
