製品名DAB Substrate Kit
DAB substrate kit for IHC staining using peroxidase-based detection (ab64238). Ideal for autostainers as reagent is stable for up to 6 hours after mixing the two components.
3,3'Diaminobenzidine (DAB) is a widely used chromogen for immunohistochemical staining. In the presence of peroxidase enzyme, 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.

Our Abpromise guarantee covers the use of ab64238 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-P||Use at an assay dependent dilution.|
Immunohistochemical analysis of healthy and colitis mouse colon sections (untreated and treated with enoxaparin) labeling claudin-4 with ab15104 at 1/200. ab7090, anti-rabbit immunoglobulin G conjugated to horseradish peroxidase (HRP) at 1/300 was used as the secondary antibody. ab64238 at 1/50 was used to develop the histological signal.
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.
Control, C; untreated colitis, DSS; oral enoxaparin, OE; intraperitoneal injection of enoxaparin, IPE.
Immuno-staining of formalin–fixed and paraffin-embedded liver sections with ab64238. Secontions were obtained from control (saline) and treated with CCl4+CT-N and CCl4+AD-N (left) and antibody control (right).
Immunohistochemical analysis of mouse lung. 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.
(A) A resected lung from a mouse sacrificed 28 days after SCL injection.
(B) Haemotoxylin and Eosin staining showing the tumor composed of a central area with necrosis and a peripheral zone filled with SCLs.
(C) Immunohistochemical staining for MMP-14 showing positive expression of MMP-14 in the peripheral zone of the tumor and negative in central zone.
(D) Immunohistochemical staining weak staining of MMP-2 in the peripheral zone.
