    This kit (ab80437) has been replaced by ab236469 Rabbit specific HRP/DAB Detection IHC Detection Kit - Micro-polymer.

    ab236469 is an exact copy of ab80437, except that ab236469 uses the HRP micro-polymer antibody used during the validation of Abcam's antibodies in IHC. This HRP micro-polymer antibody was identified by our R&D team as giving the most sensitive and specific staining.


    The reagents in this kit constitute a biotin-free immunoenzymatic antigen detection system. This technique involves the sequential incubation of the specimen with an unconjugated primary antibody specific to the target antigen, a rabbit specific HRP conjugate which reacts with the primary antibody, and substrate-chromogen (DAB).

  • Notes

    DAB is a suspected carcinogen. Handle with care.

    Contains hydrogen peroxide.

Our Abpromise guarantee covers the use of ab80437 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

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


  • Immunohistochemical analysis of mouse lung tissue labeling Ki67 detected with ab80437. Tissue sections were embedded in paraffin and were counterstained with hematoxylin. 


  • Immunohistochemical (frozen) analysis of MC38 tumor sections labeling CD3 with ab16669 at 1/400 dilution. Sections were fixed with acetone, treated with peroxidase block 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.






  • ab18723 staining 6 week rat brain tissue subventricular zone (SVZ) by IHC-P using rabbit-specific EXPOSE IHC detection kit (ab80437). Formalin fixed paraffin embedded tissue sections were pre-treated using heat mediated antigen retrieval (using a pressure cooker) with sodium citrate buffer (pH6) for 30 mins. The section was incubated with ab18723, 0.1µg/ml, for 1 hour at room temperature. DAB was used as the chromogen and the section was counterstained with haematoxylin and mounted with DPX.

ab64226 is the protein block used in ab80437. A link to ab64226 is below:

The Goat anti-rabbit HRP conjugate in ab80437 is pre-adsorbed against mouse IgG, so it should not cross react with mouse tissue.

I have contacted the lab who have agreed to add the blocking peptide for ab37542 to the catalogue. The product is called BAIAP2 peptide, ab170411.
