SMI-310_PURE_Neurofilament_Phosphorylated_Antibody_1_123118_updated.png
IHC staining of purified anti-Neurofilament H & M (NF-H/NF-M), Phosphorylated antibody (clone SMI 310) on formalin-fixed paraffin-embedded rat brain tissue. Following antigen retrieval using Retrieve-All Antigen Unmasking System 3: Acidic, 100X (Cat. No. 927601), the tissue was incubated with 0.5 µg/ml of the primary antibody for 60 minutes at room temperature. BioLegend's Ultra-Streptavidin (USA) HRP 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: 50 µm

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 regulate 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-L) runs at 68-70 kD; the medium or middle (NF-M) runs at about 145-160 kD; the heavy or highest (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 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 glia (negative for NF).

Recommended Usage

For immunohistochemistry, a concentration range of 0.5 - 10 μg/ml is suggested. For Western blotting, the suggested use of this reagent is 0.5 - 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 blotting4, immunocytochemistry2, immunohistochemical staining of frozen tissue sections1,3, and spatial biology (IBEX)5,6.

 

Clone SMI 310 reacts with an extensively phosphorylated epitope of neurofilament H and, to a much lesser extent, neurofilament M in most mammalian species. Phosphatase treatment of samples abolishes reaction with SMI 310. A very extensive degree of hyperphosphorylation of neurofilaments seems to be necessary for its reactivity.

Antigen Details

Structure
The medium or middle neurofilament (NF-M) runs at 145-160 kD, and the heavy or highest neurofilament (NF-H) runs at 200-220 kD.
Distribution

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

Function
Neurofilaments are the major components of the neuronal cytoskeleton. They provide axonal support and regulate axon diameter.
