  • Title: Neurofilament proteins in fish: a study with monoclonal antibodies reacting with mammalian NF 150K and NF 200K.
    Author: Dahl D, Crosby CJ, Bignami A.
    Journal: J Comp Neurol; 1986 Aug 15; 250(3):399-402. PubMed ID: 2427556.
    Abstract:
    Monoclonal antibodies were obtained upon immunization of mice with chicken brain antigen and with the two high molecular weight neurofilament proteins (NF 150K and NF 200K) isolated from bovine spinal cord by anion exchange chromatography. By the immunoblotting procedure, the antibodies selected for this study reacted with bovine NF 150K and NF 200K. By the same procedure the antibodies reacted with sea raven, goldfish, sea bass, shark, and trout spinal cord extracts. In goldfish and sea raven the antibodies stained a single band at approximately 150 kDa and 200 kDa, respectively. Two bands were stained in the shark, sea bass, and trout. In the shark and sea bass these bands were in the molecular weight range of mammalian NF 150K and NF 200K. In the trout the upper band was approximately 150 kDa and the lower band 130 kDa. Our findings suggest an early origin of NF 150K and NF 200K in vertebrate phylogeny as well as considerable divergence in several species.
