Hydrogen Peroxide Blocking Reagent

製品の詳細

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.

3. 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 (or 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 (or 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 or 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.
