[Histonet] Counterstain for dual chromogenic

[Eva Permaul]

Good morning,
I have been attempting to do some dual chromogenic staining. I am using 
a mouse and a rabbit antibody. For the mouse antibody I am using an 
HRP-mouse secondary followed by AEC for visualization. For the rabbit 
antibody I am using a biotinylated rabbit secondary, followed by ABC-AP 
and vector blue. My problem is what to use as a counterstain. From 
everything I have read so far there isn't one that would work without 
having some problems. I was thinking of trying a very light Hematoxylin 
and see if it doesn't disrupt the vector blue visualization too much. 
Does anyone else have any suggestions?
Thanks,
Eva
