Provided below are ELISA kits targeting neurofilament medium, a human protein encoded by NEFM. This protein is 916 amino acids long, with a mass of 102.5 kDa, and is a member of the Intermediate filament family. 2 isoforms have been identified. Glycosylation sites have been reported. Other alias names for this protein include: neurofilament medium polypeptide, 160 kDa neurofilament protein, neurofilament 3, neurofilament triplet M protein, neurofilament-3 (150 kD medium), NEF3, and NF-M. ELISA kits are available that are reactive to human, rat, and bovine variants of the target antigen.
