製品の概要
DAB substrate kit ab64238 is used for IHC staining using HRP / peroxidase enzyme for detection. Reagent is stable for up to 6 hours after mixing the two components.
DAB (3,3'Diaminobenzidine) is the most commonly used chromogen for immunohistochemical staining. In the presence of HRP / peroxidase, DAB produces a brown precipitate that is insoluble in alcohol.
This product is a two component form consisting of a liquid, refrigerator stable DAB Chromogen and DAB Substrate.
IHC protocol suitable for use with DAB substrate kit:
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 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 ab64238 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.

Antigen retrieval was performed by incubating the sections for 10 minutes at 97°C in 1 mM EDTA buffer, pH 8.0 or 10 mM citrate buffer, pH 6.0.

Samples were fixed in 10% buffered formalin, paraffinized and sliced at 1.5 µm thick. Antigen retrieval was performed using ab64214 for the deparaffinized slices. Sections were blocked with 2% normal goat serum, PBS(-) and 0.1% Tween20. They were then incubated with the primary antibodies for 1 hour at 4°C and with secondary antibodies for 30 minutes at room temperature. The avidin-biotin-peroxidase complex method with peroxidase streptavidin and the DAB substrate kit ab64238 was performed.
