This antibody reacts with 200 kDa subunit protein of human neurofilament. It specifically recognizes a nonphosphorylated epitope in the tail domain of NF-H. Dephosphorylation of NF-H will increase immunoreactivity with this antibody.
This antibody is suitable for immunohistochemical staining of Bouin's and alcohol-fixed paraffin-embedded or frozen tissue sections. To stain, incubate 30-60 minutes at room temperature or overnight at 4°C.
Neurofilaments are the intermediate (10-12 nm) filament proteins (IFPs) located specifically in neurons, and are composed predominantly of three classes/subunits of neurofilaments: NF-L (low molecular weight; 68 kDa), NF-M (medium molecular weight; 160 kDa), and NF-H (high molecular weight; 200 kDa), with some variation in different species. The neurofilaments are long helical proteins involved in the maintenance of neuronal caliber, which polymerize to form a rigid cytoskeleton in the neuron. Like most other IFPs, the expression of the different neuronal IFPs is both tissue-specific and developmentally regulated. This polymerized network is composed of all three filaments, and the stoichiometry of association varies during development. Neurofilaments are posttranslationally modified both by phosphorylation and glycosylation. Like other intermediate filament proteins, phosphorylation likely mediates neurofilament dynamics. However, how O-linked N-acetylglucosamine residues function to modify neurofilament function remains unclear. The NF-H polyclonal antibody can be used to identify neurons and their processes in tissue sections and in tissue culture and the antibody can also be used to study microfilament accumulations seen in many neurological diseases, such as Lou Gehrig's disease or Alzheimer's disease.
