General notes
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.

Immunohistochemistry (Frozen sections) - Hydrogen Peroxide Blocking Reagent (ab64218)Selby M.J et al., PLoS One 11(9), Fig 2. doi: 10.1371/journal.pone.0161779. Reproduced under the Creative Commons license http://creativecommons.org/licenses/by/4.0/
Immunohistochemical (frozen) analysis of MC38 tumor sections labeling CD3 with ab16669 at 1/400 dilution. Sections were fixed with acetone, treated with peroxidase block (ab64218) to quench endogenous peroxidase, and then further blocked with a 10% goat serum and 5% BSA solution. CD3 positive T cells were detected using ab80437. Invasive margin (top) shows sections derived from the periphery of the tumor and interior (bottom) shows sections from within the tumor.
