Beta Galactosidase Antibody Staining Protocol for Immunohistochemistry
Description: Beta galactosidase is a a metalloenzyme that that splits lactose into glucose and galactose and is coded by a gene (lac z) in the lac operon of Escherichia coli.
Primary Antibody
|
Name: Beta galactosidase Antibody |
|
Clone: Rabbit polyclonal |
|
Supplier: Abcam |
|
Catalog Number: ab616 |
|
Dilution: 1:500 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: Nulcear |
| Images: Search image |
Additional Information:
| Tissue Type: Tissue or cells expressing LacZ or Transgenic mice expressing nuclear beta-galactosidase |
| Fixation: Formalin-fixed paraffin sections, or paraformaldehyde fixed frozen sections |
| Positive Control: Tissue or cells expressing LacZ or Transgenic mice expressing nuclear beta-galactosidase |
| 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 |
Notes:
There is no need to perform antigen retrieval on acetone fixed frozen sections |
