Mouse Monoclonal Antibody to NF-L (Nfl, NEFL) Cat# MCA-6H112
Description
MCA-6H112 was made against the peptide GEEEDTKESEEEEKKEESAGEEQVAKKKD with an N-terminal cysteine added by which it was coupled to keyhole limpet hemocyanin. This is the C-terminal peptide of human NF-L, amino acids 514-542, see here. The properties of this antibody make is useful for western blotting, cell and tissue staining and monitoring NF-L proteolysis. The antibody works well for western blotting and for IF, ICC and IHC (for IHC see data under "Additional Info" tab). We also market several other NF-L antibodies including a rabbit and chicken polyclonal antibodies, RPCA-NF-L and a CPCA-NF-L, both made against full length recombinant human NF-L. We also have several epitope mapped mouse monoclonals including the widely used and epitope mapped MCA-DA2, see here.

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-6H112 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).
Chromogenic immunostaining of a formalin fixed paraffin embedded human cerebellum section with mouse mAb to NF-L, MCA-6H112, dilution 1:4,000, detected with DAB (brown) using the Vector Labs ImmPRESS method and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. MCA-6H112 labels neuronal cells and their processes. This antibody performs well in testing with both 4% PFA and standard NBF fixed tissues and is our recommended clone for use in NF-L immunostaining of human tissue.vMouse select image for larger view.
