I would think that it would depend highly on which chromagen 
you're using for your IHC. I have done IHC and H&E on the same 
slide, but it does make it a lot harder to see where your 
immunostaining is(especially since I was using brown DAB). My 
immunostaining was still there, btw, it was just really hard to 
see. Perhaps try  to either get or make the DAB that turns black 
rather than brown (I think thats the nickel DAB) or use a 
chromagen thats a completely different color outside of the 
brownish, pinkish or bluish range. (I'm not sure what other 
chromogens there are since I've only used AEC and DAB but I know 
Vector makes some others.)

"You are a child of the universe, no less than the trees and the 
stars
You have a right to be here and whether or not it is clear to you, 
no doubt the universe is unfolding as it should. Therefore be at 
peace with G-d, whatever you conceive Him to be. And whatever your 
labors and aspirations,in the noisy confusion of life, keep peace 
in your soul.-Max Ehrmann,"Desiderata"
