Hello,
I might need to do a dual staing procedure on paraformaldehyde fixed 
fresh frozen sections. One marker will be stained with peroxidase (DAB). 
As a second marker for IHC I read about alkaline phosphatase (FastRed) 
which gives rise to a red color in addition to the brown color of the 
peroxidase staining. To me this combination seems to be a little bit 
unfortunate because the colors are sort of overlapping.
Does anybody know of an alternative and complimentary method for dual 
staining which might give rise to a different color other than red ? 
Unfortunately due to special circumstances Immunofluorecence is not an 
option.
Any help is much appreciated. Thanks a lot !
