Hi Paul,
Just to add another discussion topic in IHC World about DAB staining and de-staining:
http://www.ihcworld.com/smf/index.php?topic=1458.0
Hope this helps and good luck.

> The only thing I know that works for this is fish. Some breeds of tiny fish find the DAB precipitate to be quite the delicacy. Fill your Coplin jar with the purest triple-distilled water, then add fish. You need the type used in toe salons. It will take a while, so be sure to change the fish frequently. The fish must be very hungry for this to work.

They want to know if it is possible to destain the sections (remove the DAB, which is, apparently, quite dark). They have experience removing immunofluorescence antibody staining but not the DAB product.
