Neurofilament Antibody Staining Protocol for Immunohistochemistry
Description: Neurofilaments are main structural elements of neurons and their processes and are comprised of a triad of distinct proteins with molecular weights of approximately 70, 160 and 200 kDa. Anti-NF, 2F11 reacts with the phosphorylated forms of the 70 and 200 kDa components of the three major polypeptide units. The antibody shows interspecies cross-reactivity, reacting with neurofilament from other species, e.g. mouse, rat and rabbit, but does not recognize other intermediate filament proteins.

Additional Information:
| Species Reactivity: Human, rat, mouse, rabbit |
| Fixation: Formalin fixed paraffin sections, acetone fixed frozen sections, or cell smears (no antigen retrieval needed for frozen sections or cell smears) |
| Positive Control: Most of neurons and neuronal processes in central and peripheral nerves |
| Negative Control: Omit primary antibody, isotype control, absorption control |
| Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary |
