ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 1B23 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects Neurofilament M. It targets an epitope within 150 amino acids from the C-terminal region.

Immunogen

GST/His-tagged recombinant fragment corresponding to 150 amino acids from the C-terminal region of human Neurofilament M.

Application

Anti-Neurofilament M, clone 1B23 ZooMAb, Cat. No. ZRB1411, is a recombinant Rabbit monoclonal antibody that targets Neurofilament M and is tested for use in Immunocytochemistry, Immunohistochemistry, and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Neurofilament M in mouse brain tissue lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Neurofilament M in human brain tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Neurofilament M in SH-SY5Y cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Neurofilament medium polypeptide (UniProt: P07197; also known as NF-M, 160 kDa neurofilament protein, Neurofilament 3, Neurofilament triplet M protein) is encoded by the NEFM (also known as NEF3, NFM) gene (Gene ID: 4741) in human. Neurofilaments are intermediate filaments that serve as major elements of the cytoskeleton supporting the axon cytoplasm. They are the most abundant fibrillar components of the axon, being on average 3-10 times more frequent than axonal microtubules. They are built from three intertwined protofibrils, which are themselves composed of two tetrameric protofilament complexes of monomeric proteins. The neurofilament triplet proteins (68/70, 160, and 200 kDa) occur in both the central and peripheral nervous system and are usually neuron specific. The 68/70 kDa NF-L protein can self-assemble into a filamentous structure, however the 160 kDa NF-M and 200 kDa NF-H proteins require the presence of the 68/70 kDa NF-L protein to co-assemble. Neurofilaments contain a number of repeats of the tripeptide KSP (Lys-Ser-Pro) and NF-M is phosphorylated on a number of the serines in this motif by protein kinase A and C. Phosphorylation of NF-M results in the formation of interfilament cross bridges that are important in the maintenance of axonal caliber. Deletion of the phosphorylated tail domain of NF-M is reported to inhibit radial growth of axons and reduce their conduction velocities. However, mice expressing NF-M subunits that lack phosphorylation at KSP sites along the tail domain have normal axon calibers and conduction velocities, indicating that the NF-M tail domain, but not tail phosphorylation is crucial for axon radial growth. The level of phosphorylation is shown to be altered developmentally and coincides with a change in the neurofilament function. Mutations in the rod domain region of NF-M have been identified in early onset Parkinson s disease. Also, in the brains of Alzheimer s disease patients, a reciprocal relationship between O-GlcNAcylation and phosphorylation of N-FM has been reported where a decreased O-GlcNAcylation is accompanied with increased KSP phosphorylation of NF-M. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
