CD5 Antibody Staining Protocol for Immunohistochemistry
Description: CD5 antigen, a molecule of 67kD, is expressed on activated T cells, most of thymocytes, a subset of B cells and a large proportion of peripheral blood lymphocytes. In lymph nodes, the main reactivity is seen in T cell areas and on occasional cells in B cell regions, particularly in mantle zones.
Primary Antibody

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 |

Results:
| Staining Pattern: Membrane |
| Images: Search image |
Additional Information:
| Tissue Type: Tonsil |
| Fixation: Formalin fixed paraffin sections |
| Positive Control: Tonsil |
| Negative Control: Omit primary antibody, isotype control or 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 |
