Neurofilament-H (RMdO 20) Mouse mAb #2836
|W IP IHC-P IF-F||H M R||Endogenous||180-220||Mouse IgG1|
Reactivity Key: H=Human M=Mouse R=Rat
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Neurofilament-H (RMdO 20) Mouse mAb detects endogenous levels of total Neurofilament-H protein. Neurofilament-H (RMdO 20) Mouse mAb has been reported to detect NFM and NFH in human samples but only NFH in mouse, rat or bovine samples (Lee, V.M. et al., 1988).
Source / Purification
Monoclonal antibody is produced by immunizing animals with rat neurofilament.

The cytoskeleton consists of three types of cytosolic fibers: actin microfilaments, intermediate filaments, and microtubules. Neurofilaments are the major intermediate filaments found in neurons and consist of light (NFL), medium (NFM), and heavy (NFH) subunits (1). Similar in structure to other intermediate filament proteins, neurofilaments have a globular amino-terminal head, a central α-helical rod domain, and a carboxy-terminal tail. A heterotetrameric unit (NFL-NFM and NFL-NFH) forms a protofilament, with eight protofilaments comprising the typical 10 nm intermediate filament (2). While neurofilaments are critical for radial axon growth and determine axon caliber, microtubules are involved in axon elongation. PKA phosphorylates the head domain of NFL and NFM to inhibit neurofilament assembly (3,4). Research studies have shown neurofilament accumulations in many human neurological disorders including Parkinson's disease (in Lewy bodies along with α-synuclein), Alzheimer's disease, Charcot-Marie-Tooth disease, and Amyotrophic Lateral Sclerosis (ALS) (1).
Studies of NFH (-/-) mice suggest that NFH modulates ion channel functions in large myelinated fibers (5).
