IHC staining of purified anti-Neurofilament H (NF-H), Nonphosphorylated antibody (clone SMI 32) on formalin-fixed paraffin-embedded mouse brain tissue. Following antigen retrieval using Retrieval-ALL Antigen Unmasking System 3 (Cat. No. 927601), the tissue was incubated with 1 µg/ml of the primary antibody overnight at 4°C. BioLegend’s Ultra Streptavidin (USA) HRP Detection Kit (Multi-Species, DAB, Cat. No. 929901) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50µm

Description

Neurofilaments (NF) are approximately 10 nanometer intermediate filaments found in neurons. They are a major component of the neuronal cytoskeleton, and function primarily to provide structural support for the axon and to regulate the axon diameter. There are three major NF subunits, and the names given to these subunits are based upon the apparent molecular mass of the mammalian subunits on SDS-PAGE. The light or lowest NF (NF-L) runs at 68-70 kD. The medium or middle NF (NF-M) runs at about 145-160 kD, and the heavy or highest NF (NF-H) runs at 200-220 kD. However, the actual molecular weight of these proteins is considerably lower due to the highly charged C-terminal regions of the molecules. The level of NF gene expression correlates with the axonal diameter, which controls how fast electrical signals travel down the axon. Mutant mice with NF abnormalities have phenotypes resembling amyotrophic lateral sclerosis. NF immunostaining is common in diagnostic neuropathology. It is useful for differentiating neurons (positive for NF) from the glia (negative for NF).

Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 5.0 µg/ml is suggested. For Western blotting, the suggested use of this reagent is 1.0 - 5.0 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include Western blotting6, immunohistochemistry4,5, immunocytochemistry1,2,3, 7, array tomography8.

Cross-reactivity to monkey tissue has been Reported in the literature, not verified in house4.

This antibody reacts with a nonphosphorylated epitope in neurofilament H of most mammalian species. The reaction is masked when the epitope is phosphorylated. The staining of isolated neurofilament preparations is greatly intensified upon dephosphorylation. Immunocytochemically, SMI 32 visualizes neuronal cell bodies, dendrites, and some thick axons in the central and peripheral nervous systems. However, thin axons are not revealed. Other cells and tissues are unreactive. The antibody distinguishes three subdivisions of the macaque precentral motor cortex. The greater size of the left versus the right superior temporal lobe was found to be due to increased axonal myelination and not due to increased number of glial cells or SMI 32-enumerated neurons, suggesting that the specialization for language in the left temporal lobe is related to increased speed of signal transmission. In cultures of murine cortex, SMI 32 labels a neuronal population with enhanced vulnerability to kainate toxicity most of which are GABAergic and reveal kainate-activated Ca2+ uptake.

Antigen Details

Structure
Neurofilament H has an apparent molecular mass of 200-220 kD.
Distribution

Tissue distribution: CNS, peripheral nerves and glandular cells of the prostate
Cellular distribution: Cytoskeleton, nucleus, cytosol, and mitochondrion

Function
NF-H Neurofilaments are the major components of the neuronal cytoskeleton. They provide axonal support and regulate axon diameter. Phosphorylation of NF-H results in the formation of interfilament cross bridges that are important in the maintenance of axonal caliber.
Receptors
Phosphorylation seems to play a major role in the functioning of the larger neurofilament polypeptides (NF-M and NF-H), the levels of phosphorylation result in changes to the neurofilament function.
