  • Product name
    Rabbit specific HRP/DAB (ABC) Detection IHC Kit
    See all HRP/DAB detection kit kits
  • Product overview

    The reagents in this kit constitute a labeled streptavidin-biotin immunoenzymatic antigen detection system. This technique involves the sequential incubation of the specimen with an unconjugated primary antibody specific to the target antigen, a biotinylated secondary antibody which reacts with the primary antibody, enzyme-labeled streptavidin, and substrate-chromogen.

  • Notes

    DAB is a suspected carcinogen. Handle with care.

    Contains hydrogen peroxide

Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
IHC-Fr Use at an assay dependent concentration.


  • Immunohistochemical analysis staining TNF or IL6 in mouse tissue sections.  Samples are incubated in murine TNF (ab9739) or IL6 primary antibody. Bound primary antibodies were detected using IHC detection kit (ab64261). Immunohistochemistry was used to determine the effect of uridine on synovial expression of TNF and IL6. 

  • Immunohistochemical analysis of KLF4 and pVHL expression in colon cancer tissues. Sections from colon cancer and adjacent tissues were analyzed by immunostaining against KLF4 and pVHL. Staining without primary antibody served as negative control.

    Tissue sections were de-waxed with xylene and rehydrated through gradient ethanol into water. For antigen retrieval, sections were heated in citrate buffer (pH6.0) for 10 min at 95°C in a microwave oven. After cooling to room temperature, the sections were then digested with 0.05% trypsin for 10 min at 37°C. Endogenous peroxidase activity was quenched with 0.3% H2O2 in methanol for 30 min at room temperature. After PBS washes, nonspecific antibody binding was blocked by pre-incubating slides with 10% normal goat non-immune serum at 37° for 30 min. After blotting off the blocking serum, sections were incubated with primary antibody against LKF4 as well as primary antibody against VHL at 4° overnight. After PBS washes again, sections were incubated with biotinylated secondary antibody at 1:200 dilution for 30 min at room temperature. After incubating with Vectastain ABC reagent (Vector Laboratories, Inc., Burlingame, CA) for 30 min at room temperature, the sections were developed with Anti Rabbit HRP/DAB Detection Kit (ab64261). Sections were washed in running tap water and lightly counterstained with hematoxylin, followed by dehydration and coverslip mounting. Negative controls were obtained by omitting the primary antibody.

  • Human colon carcinoma fixed in 10% NBF for 24 hrs and stained with anti p53 antibody using Anti Rabbit HRP/DAB Detection Kit (ab64261).

This issue may be result of sample preparation. It is oftentimes the case that the slides have not been inadequate deparaffinization which will lead to this type of staining. The link below outlines Abcam recommendations of deparaffinization: https:...

One drop of DAB chromogen is about 30 ul, and it is to be added to 1.5 ml of the substrate (50 drops). So the ratio is 1:50.

The mixture cannot be stored very long once you have made it. Ideally, you should mix it immediately before using it...

I can confirm the Protein Block is a PBS solution with 0.5% Casein and 0.5% BSA.

I hope this information will be helpful for your customer.
Have a great day!

Great product that gives best results each time.

Excellent Excellent 5/5 (Ease of Use)
We are very happy using this kit. Every time without fail we get strong signals. perfectly drafted protocol for easy use. Needs optimization with time of incubation depending on the immunoreactivity and intensity of your primary antibody.

Thank you for getting in touch.

When using frozen sections, you can use a general frozen section staining protocol. I would amend the protocol booklet protocol as follows:

1. Fix the sections (for example 4% PFA for 10 minutes or ice ...

It is very easy to use, get sharp images with it.

Excellent Excellent 5/5 (Ease of Use)
This kit is very easy to use, just follow its instructions. It contains protein block, secondary antibody and substrate et al. in one box, basically everything you need for IHC except primary antibody. The box of the kit is of the right size, not too big not too small, so it is very easy to locate in the refrigerator. I wish the kit also contains Hematoxylin but it doesn't. The staining results are sharp and strong.

I am sorry that I was unavailable when you called but am glad to hear from you. We would not suggest using 5% BSA instead of the protein block included with the kit. These blocking solutions are formulated to give the best result with the kit. I...

It does look like endothelium is stained, as expected, but yes, the background is high. Did you include a negative control, staining with just the secondary detection kit, and not the primary? If that is completely negative, and shows no background, th...
