Neurofilaments are the 10nm or intermediate filament proteins found specifically in neurons, and are composed predominantly of three major proteins called NF-L, NF-M and NF-H, though other filament proteins may be included also. The major function of neurofilaments is likely to control the diameter of large axons (1). NF-L is the neurofilament light or low molecular weight polypeptide and runs on SDS-PAGE gels at 68-70kDa with some variability across species. Antibodies to NF-L like MCA-DA2 are useful for identifying neuronal cells and their processes in cell culture and sectioned material. NF-L antibody can also be useful for the visualization of neurofilament rich accumulations seen in many neurological diseases, such as Lou Gehrig’s disease (ALS), giant axon neuropathy, Charcot-Marie Tooth disease and others (2-4). Much interest has recently been focused on the detection of NF-L released from neurons into blood and CSF as a surrogate marker of primarily axonal loss in a variety of types of CNS injury and degeneration (5).
RPCA-NF-L antibody was made against a preparation of recombinant full length human NF-L and binds NF-L from a variety of mammalian species including human, rat and mouse. We also generated a highly specific chicken polyclonal antibody, CPCA-NF-L, a rabbit polyclonal antibody to the C-terminal peptide of rat NF-L protein, RPCA-NF-L-ct and mouse monoclonal antibodies, MCA-DA2, MCA-7D1, MCA-1B11, and MCA-6H112.

Chromogenic immunostaining of a formalin fixed paraffin embedded human cerebellum section with rabbit pAb to NF-L, RPCA-NF-L, dilution 1:5,000, detected with DAB (brown) using the Vector Labs ImmPRESS method and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. In this image, RPCA-NF-L labels the perinkarya and dendrites of Purkinje cells and the projections of neuronal cells within the granular layer. This antibody performs well in testing with both 4% PFA and standard NBF fixed rat, mouse and human tissues. Mouse select image for larger view.
