Neurofilament (NF 200kD, NF-200, NF-H, NF)

Neurofilaments (NFs), the intermediate filaments (IFs) specific to neurons, is the predominant cytoskeletal elements in many nerve cells. They are believed not only to confer mechanical stability, but also to play a role in determining axonal caliber. The human NF-H gene has three introns, two of which interrupt the protein-coding sequence at identical points to introns in the genes for the two smaller Neurofilament proteins, NF-M and NF-L having mol. wts predicted from their gene sequences of -110 000, -102 000 and -62 000 respectively. Each type of Neurofilament contains a central a-helical 'rod' domain of -310 amino acids, characterized by a heptad repeat in the amino acid sequence in which the first and fourth residues are apolar. Perikaryal NFs are predominantly unphosphorylated, while axonal NFs are highly phosphorylated. Defect in NFH causes susceptibility to amyotrophic lateral sclerosis. It has an important function in mature axons.\n\nApplications: \nSuitable for use in Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nImmunohistochemistry(Paraffin): 1:200-1:400\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.
