CD15 Antibody Staining Protocol for Immunohistochemistry
Description: CD15 recognizes a human myelomonocytic antigen. The CD15 antigen is present on greater than 95% of mature peripheral blood eosinophils and neutrophils and is present at low density on circulating monocytes. In lymphoid tissue, CD15 reacts with Reed-Sternberg cells of Hodgkin's disease and with granulocytes; however, CD15 reacts with few tissue macrophages and does not react with dendritic cells.
Primary Antibody
|
Name: CD15 Antibody |
|
Clone: C3D-1, Mouse anti-Human |
|
Supplier: Dako |
|
Catalog Number: M0733 |
|
Dilution: 1:20 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: 60min/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: Membrane/cytoplasmic |
| Images: Search image |
Additional Information:
| Tissue Type: Tonsil |
| Fixation: Formalin fixed paraffin sections, or acetone fixed frozen 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 |
Notes:
|
1. There is no need to perform antigen retrieval for acetone fixed frozen sections 2. CD15 (Clone MMA) from Becton Dickinson (Cat# 347420) also works well at 1:20 dilution |
