Provided below are ELISA kits targeting neurofilament light, a human protein encoded by NEFL. This protein is 543 amino acids long, with a mass of 61.5 kDa, and is a member of the Intermediate filament family. There is a noted implication in Charcot-Marie-Tooth disease 1F. Other alias names for this protein include: neurofilament light polypeptide, light molecular weight neurofilament protein, neurofilament protein light chain, neurofilament subunit NF-L, neurofilament light polypeptide 68kDa, protein phosphatase 1 regulatory subunit 110, and CMT1F. ELISA kits are available that are reactive to human and rat variants of the target antigen.
