Neurofilament H (Neurofilament Heavy Polypeptide, NF-H, Neurofilament Triplet H Protein, 200kD Neurofilament Protein, NEFH, NFH)

Neurofilaments can be defined as the intermediate or 10nm filaments found in specifically in neuronal cells. In the electron microscope neurofilaments appears as 10nm diameter fibres of indeterminate length which generally have fine wispy protrusions from their sides. They are found particularly abundantly in axons of large projection neurons. They probably function to provide structural support for neurons and their synapses and to support the large axon diameters required for rapid conduction of impulses down axons. They are composed a mixture of subunits which usually include the three neurofilament triplet proteins, known as NF-L, NF-M and NF-H. Neurofilaments may also include smaller amounts of peripherin, alpha-internexin, nestin and in some cases vimentin. Antibodies to the various neurofilament subunits are very useful cell type markers since the proteins are among the most abundant of the nervous system, are expressed only in neurons, and are biochemically very stable. The HGNC name for this protein is NEFH.\n\nApplications:\nSuitable for use in ELISA (capture), Immunofluorescence and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nImmunofluorescence: 1:100,000\nWestern Blot: 1:1,000,000\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Additional Info

Recognizes bovine and rat NF-H. Binds primarily to the phosphorylated axonal forms of NF-H. As with many antibodies to NF-H, this antibody has some cross-reactivity with phosphorylated NF-M, which has similar phosphorylation sites to NF-H.
