IHC staining of anti-Neurofilament H & M (NF-H/NF-M), Hypophosphorylated antibody (clone SMI 35) on formalin-fixed paraffin-embedded rat cerebellum tissue. Following antigen retrieval using Retrieve-All Antigen Unmasking System 3: Acidic, 100X (Cat. No. 927601), the tissue was incubated with 5 µg/mL of the primary antibody overnight at 4°C, followed by incubation with 2.5 µg/mL Alexa Fluor® 488 Goat anti-mouse IgG antibody (Cat. No. 405319) for one hour at room temperature. The image was captured with a 40x objective. Scale bar: 20 µm.

Description

Neurofilaments (NFs) 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 neurofilament (NF-L) runs at 68-70 kD. The medium or middle (NF-M) runs at about 145-160 kD, and 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 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 0.5 - 5.0 µg/mL is suggested. For western blotting, the suggested use of this reagent is 1.0 - 5.0 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats of this clone): include ELISA Capture1-3, immunohistochemical staining on frozen tissue sections, immunofluorescence staining, and spatial biology (IBEX)6,7.

Clone SMI 35 reacts with highly phosphorylated neurofilaments, as well as with low degrees of phosphorylation. It primarily reacts with neurofilament H and with neurofilament M to a lesser extent.

Notes: On two dimensional gels, this antibody detects a band extending from the phosphorylated neurofilament position at 200 kD (pI 5.1) toward the non-phosphorylated position at 170 kD (pI 6.2).
