I have been asked to review some two year-old immuno slides.  Most of the slides are very faded to completely faded.  I have no idea what brand DAB they were using.  

Has anyone tried to re-stain previously DAB stained immuno slides?  I have to use DAB, I cannot switch chromogens.

Is there some way to remove the faded DAB?

Thanks,
