Scientific Data Images for NF-M Antibody (3H11)

Western Blot: NF-M Antibody (3H11) [NB300-134]

Western Blot: NF-M Antibody (3H11) [NB300-134]

Western Blot: NF-M Antibody (3H11) [NB300-134] - Neuronal tissue lysates using mouse mAb to NF-M, dilution 1:10,000 in green: [1] protein standard (red), [2] rat spinal cord, [3] mouse spinal cord, [4] cow spinal cord, [5] rat sciatic nerve. Strong bands at ~145 kDa corresponds to rodent NF-M while that at about 160 kDa corresponds to the significantly larger bovine NF-M protein.
Immunohistochemistry Free-Floating: NF-M Antibody (3H11) [NB300-134]

Immunohistochemistry Free-Floating: NF-M Antibody (3H11) [NB300-134]

Immunohistochemistry Free-Floating: NF-M Antibody (3H11) [NB300-134] - Adult rat frontal cortex section stained with mouse mAb to neurofilament NF-M, dilution 1:5,000 in green, and costained with chicken pAb to neurofilament NF-H, dilution 1:5,000 in red. Following transcardial perfusion of rat with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45uM, and free-floating sections were stained with above antibodies. NB300-134 antibody labels neuron cell bodies and dendrites of pyramidal neurons, as well as dendrites and axons of other neuronal cells, while the NF-H antibody stains the network of neuronal axons only.

Background: NF-M

Neuronal intermediate filaments (NIF) are type-IV intermediate filaments found specifically on neurons where they play key role in maintaining neuronal morphology as well as in regenerating myelinated axons. NIF contain three subunits: a light polypeptide (NEFL/NFL), a medium polypeptide (NEFM/NFM), and a heavy polypeptide (NEFH/NFH), with molecular weights of 68, 160, and 212 kD respectively. Mature NIFs are heteropolymers with about 4:2:1 stoichiometric ratio of NEFL: NEFM: NEFH and also contain a fourth type-IV intermediate filament (IF) subunit, alpha-internexin. NEFM is essential to cross-bridge formation, stabilization, and longitudinal extension of filamentous network and is more critical than NEFH in regulating NIF's structure and function. NEFM is crucial for the acquisition of normal axonal caliber in response to a myelin-dependent "outside-in" trigger for radial axonal growth and removal of the tail domain as well as lysine-serine-proline (KSP) repeats of NEFM, but not NEFH, produces axons with impaired radial growth and reduced conduction velocities. Moreover, mutations of NEFM have been associated with CNS/PNS disorders such as ALS, Parkinson's disease etc., and an imbalance in NEFM's O-GlcNAcylation - phosphorylation regulation plays a crucial role in in Alzheimer disease.
