I don't recall this question, but I would be interested in how you get
around the problem of epidermal pigmentation if you are looking for
protein expression in the epidermis; do you bleach the tissue (and if
so, does that affect antigenicity of the proteins), or can you choose a
detection chromogen that has a wild color, like a Barney purple color? 

Thanks for your help.



We use Vectors Nova Red and it works well with melanin and also
