Could you give us a few facts from your protocol? They may help pin down
what might be causing your edge effect.
How long does your tissue stay on the grossing/trimming table before being
put into fixative?
What type of fixative are you using? How fresh is it?
How long to you fix?
What temps to you perform IHC at?
How long are your incubations?

I am having variable staining when performing IHC. I seem to get an edge
where the edge of the tissue shows increased DAB staining compared to the
of the tissue. I have tried testing many fixation variables and still
found an edge affect culprit. I'm wondering if anyone in the community has
experienced and corrected this problem. Thanks for you help!
