Neurofilaments (NF) are approximately 10 nanometer intermediate filaments found in neurons. They are a major component of the neuronal cytoskeleton and their function is primarily to provide structural support for the axon and to 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, 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 glia (negative for NF).

- Storage & Handling
- Store at -20°C. Upon initial thawing, apportion into working aliquots and store at -20°C. Avoid repeated freeze-thaw cycles to prevent denaturing the antibody. For long-term storage, keep the antibody at -80°C.
- Application
-
IHC-P - Quality tested
WB - Verified
IHC-F, ICC - Reported in the literature, not verified in house - Recommended Usage
-
Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a dilution range of 1:1000 - 1:5000 is suggested. For Western blotting, the suggested use of this reagent is 1:5000 - 1:10000 per ml. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
SMI 311 has been selected to provide a specific marker for neurons in tissue sections and cultures. In contrast to individual antinonphosphoneurofilaments that identify different subset of neurons and are, therefore, especially suitable for defining anatomic and functional differences in normal and pathologic neurons, SMI 311 is a convenient marker for neurons in general and their differentiation from non-neuronal cells. SMI 311 provides an early marker of neuronal migration and differentiation in human fetal development yielding Golgi-like images without the disadvantages of lack of selectivity and poor specificity of the Golgi technique. In specifically delineating cell bodies and dendrites, SMI 311 has been used to trace the "inside-out gradient" of neuron production and differentiation. Pathologic conditions, such as undernutrition affect SMI 311-visualized soma size and dendritic arborization.
