Product details:
Hydrogen Peroxide Blocking Reagent ab64218 for use in IHC with detection based on HRP / peroxidase.
Note: The concentration of hydrogen peroxide in this product is 0.3%.
IHC protocol suitable for use with Hydrogen Peroxide Blocking Reagent:
For frozen sections, skip steps 1 and 2.
1. Deparaffinize and rehydrate formalin-fixed paraffin-embedded tissue section.
2. Use appropriate
antigen retrieval buffer or enzyme
(primary antibody dependent) to treat sections. Wash 3 times in buffer.
Add enough hydrogen peroxide blocking solution ab64218 to cover the sections. Incubate for 10 minutes.
Wash 2 times in buffer. If necessary, use
avidin biotin blocking
4. Apply
protein block
normal serum
from same species as secondary antibody) and incubate for 5 minutes at room temperature to block nonspecific background staining. Wash once in buffer.
5. Apply primary antibody in
antibody diluent
and incubate.
6. Wash 4 times in buffer. Incubate slide with
biotinylated secondary antibody
HRP polymer secondary antibody
and skip step 7). Wash 4 times in buffer.
7. Apply
streptavidin-HRP
and incubate for 10 minutes at room temperature.
8. Rinse 4 times in buffer. Place slide in
DAB substrate
AEC substrate
and incubate until desired color is achieved (1-10 mins). Rinse 4 times in buffer.
9. Add enough drops of
hematoxylin
to cover the section. Incubate for 1 minute.
10. Rinse 7-8 times in tap water. Add
mounting medium
to cover the section.
