NeuN Antibody Staining Protocol for Immunohistochemistry
Description: NeuN (or Neuronal Nuclei) reacts with most neuronal cell types throughout the nervous system of mice including cerebellum, cerebral cortex, hippocampus, thalamus, spinal cord and neurons in the peripheral nervous system including dorsal root ganglia, sympathetic chain ganglia and enteric ganglia. Developmentally, immunoreactivity is first observed shortly after neurons have become postmitotic, no staining has been observed in proliferative zones. The immunohistochemical staining is primarily localized in the nucleus of the neurons with lighter staining in the cytoplasm. The few cell types not reactive with MAB377 include Purkinje, mitral and photoreceptor cells. The antibody is also an excellent marker for neurons in primary cultures and in retinoic acid-stimulated P19 cells as well as for identifying neurons in transplants.
Primary Antibody
|
Name: NeuN Antibody |
|
Clone: Mouse monoclonal |
|
Supplier: Chemicon |
|
Catalog Number: MAB377 |
|
Dilution: 1:600 using IHC-TekTM Antibody Diluent (Cat# IW-1000 or IW-1001) to reduce background and unspecific staining and serum blocking step is NOT needed. |
|
Incubation Time/Temp: 60 min/room temperature |
Antigen Retrieval
| Device: IHC-TekTM Epitope Retrieval Steamer Set (Cat# IW-1102) |
| Buffer/pH value: IHC-TekTM Epitope Retrieval Solution (Cat# IW-1100) |
| Heat/Cool Temperature: 95-100 ºC/room temperature |
| Heat/Cool Time: 20 minutes/20 minutes |
Detection Methods
| Standard Method: ABC Method or LSAB Method |
| Enhanced Method: Polymeric Methods |
Chromogen Substrate
| Reagent: DAB |
| Incubation Time/Temperature: 1-3 minutes/room temperature |
Counterstain
| Reagent: Mayer's Hematoxylin |
| Staining Time: 30 seconds |
Results:
| Staining Pattern: Nuclear/cytoplasmic (primarily in nuclei with lighter staining in the cytoplasm) |
| Images: Search image |
Additional Information:
| Species Reactivity: Human, mouse, rat, ferret, chick, salamander |
| Fixation: Formalin fixed paraffin sections. For staining of cultured cells, permeablizing with Triton X-100 is needed and lower dilution (1:100) is required. |
| Positive Control: Brain |
| 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 |
