  • Product overview

    Rabbit specific HRP/AEC (ABC) IHC Detection Kit ab64260 is a complete kit to detect a primary antibody raised in rabbit, using HRP-labeled-streptavidin and a biotinylated anti-rabbit secondary antibody.

    It is supplied with a full protocol and with peroxidase and protein blocking reagents, biotinylated secondary antibody, streptavidin-HRP, and AEC substrate.

    In the method:
    - a sample is incubated with an unconjugated primary antibody specific to the target antigen
    - a biotinylated secondary antibody then binds to the primary antibody
    - HRP-labeled streptavidin then binds to the secondary antibody
    - the HRP produces a colored substance at the site of primary antibody binding by reacting with AEC.

  • Relevance

    An HRP/AEC Detection Kit is a labeled immunoenzymatic antigen detection system. Horseradish peroxidase (HRP) readily combines with hydrogen peroxide (H2O2) and the resultant complex can oxidize a wide variety of chromogenic substrates. AEC is 3-amino-9-ethyl-carbazole, a chromogenic substrate.

Thank you for replying with that information.

As I mentioned over the phone, I have spoken to the source of these kits and we do not have any experimental data using either the ACE or DABdetection kits (ab64260, ab64261, ab80437 and ab94361)for IHC on fresh PBMC samples, asallof these kits have only been tested on formalin fixed paraffin embedded tissue samples.Wewould expect that as long as the primary antibody binds the target as expected that both kits could be suitable foryour samples but as we have not tested it ourselves we would not be able to guarentee this.

There should be good contrast if using the AEC or DAB kit with hematoxylin as counterstain. We counterstain with hematoxylin in-house regardless ofwhether DAB or AEC is used. The sensitivity betweenAEC and DABis similar. I would recommend using ab94361 or ab80437 if you expect the PBMC samples to contain any endogenous biotin.I am sorry but I cannot recommend a particular supplier of hematoxylin.

And to answer your final question, the mounting media ab64230 should be suitable for your purposes.

I hope this information has been of help. If you require any further information please do not hesitate to contact us again.

Our ab93705 (Mouse and Rabbit Specific HRP/AEC (ABC) Detection IHC Kit) is not suitable for use on mouse samples. The secondary antibody is a cocktail of biotinylated anti-mouse and anti-rabbit antibodies and the anti-mouse antibodies will react with endogenous Ig in the mouse samples. The blocking reagent will not prevent that staining.

If the customer is using a rabbit primary antibody I would recommend that they use our ab64260 (Rabbit specific HRP/AEC (ABC) Detection IHC Kit) instead:
