Provided below are ELISA kits targeting neurofilament heavy, a human protein encoded by NEFH. This protein is 1026 amino acids long, with a mass of 112.5 kDa, and is a member of the Intermediate filament family. 2 isoforms have been identified. This is reported to be a cytoplasmic protein. There is a noted implication in Amyotrophic lateral sclerosis. Other alias names for this protein include: neurofilament heavy polypeptide, 200 kDa neurofilament protein, NF-H, neurofilament triplet H protein, CMT2CC, and NFH. ELISA kits are available that are reactive to human, mouse, rat, bovine, primate, plant, and other mammalian variants of the target antigen.
