Images & Validation

• Tested Applications: ICC, IF, IHC, WB
• Dilution Range: WB: 1:10000-1:20000; IHC: 1:1000-1:2000; ICC: 1:1000-1:2000
• Reactivity: Bovine, Human, Mouse, Porcine, Rat
• Application Notes:
  The antibody recognizes NF-L in reduced Westerns regardless of the disease state. Block and permeabilize sections in 5-10% normal goat serum or serum of the species the secondary antibodies were made in, in PBS plus 1% Triton-100 (PBST) for 1 hour with slight agitation, followed by primary antibody incubations and fluorescent secondary identification. High primary antibody dilutions require refrigerated, overnight incubations for best results. Recommended fixation is 4% PFA fixed, frozen tissue 20-50 microns; other fixation methods have not been tested and are not recommended at this time. Degeneration-specific detection is fixation, antigen recovery, and concentration-dependent. The epitope detected a proprietary recombinant immunogen based on the Coil 2 region of human NF-L. This peptide epitope can be uncovered in degenerating cells but not normal cells. However, Clone 1B11 can bind normal neurofilaments when used at high concentrations but shows strong binding to degenerated material at lower antibody concentrations. The specific reactivity of this epitope is sensitive to tissue treatments and could become exposed in healthy cells under some conditions. For example, treatment of the fixed tissue with high temperatures, proteinase, or other denaturants may cause the reactive epitope to become exposed in healthy cells, leading to a false positive. Biosensis recommends experimenting with treated and untreated tissues when first using these antibodies if degeneration specificity is desired. The exact conditions and dilutions must be determined experimentally by the end user. This antibody will detect NL-L protein in paraffin-embedded rodent tissues; however, the degeneration-specific detection can be problematic in paraffin tissues, particularly if Heat-Induced Epitope Retrieval (HIER), or other common antigen recovery methods are used. This is because the reactive epitope, which is covered in healthy cells but exposed in degenerative cells, could become accessible to the antibody in healthy cells, leading to false positives. For this reason, paraffin-embedded tissues are not recommended if degeneration-specific detection is desired. This antibody was made against NF-L purified from pig spinal cord and binds to amino acids 316-370 of human NF-L
