Dear Histo-netters,

I am trying to work up a phosphor-akt antibody (Cell Signaling #3787)
for my FFPE blocks of mouse uterine tubules.  Fixation is in Z-fix for
48 hours.  So far I have tried HIER with both microwave retrieval  and a
pressure-cooker.  I am using DAKO's En-vision plus rabbit secondary HRP
conjugate and reacting with DAB.  The results are less than impressive,
although I am seeing some low level staining at 1:50.  Has anyone used
this antibody with better success?

Thanks for any help in this matter.
