Desmin Antibody Staining Protocol for Immunohistochemistry
Description:
Desmin is a 53 kDa intermediate filament protein present in smooth
muscle cells, striated muscle cells and myocardium. In skeletal and
cardiac muscle cells, desmin filaments are localized in the Z-bands.
Primary Antibody
|
Name: Desmin Antibody |
|
Clone: Rabbit anti-Human polyclonal |
|
Supplier: Accurate Chemical & Scientific |
|
Catalog Number: YMPS31 |
|
Dilution: 1:200 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 minutes/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 ºC - 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: Cytoplasmic |
| Images: Search image |
Additional Information:
| Tissue Type: Skeletal and cardiac muscle. |
| Fixation: Formalin fixed paraffin sections, or acetone fixed frozen sections |
| Positive Control:
Skeletal
and cardiac muscle cells, smooth muscle cells of blood
vessels, viscera, the uterus as well as in Purkinje cells,
many mesangial cells of the kidney glomeruli, leiomyoma and
rhabdomyomas. |
| 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:
No need to perform antigen retrieval on frozen sections |
