I use Dako's PCNA (cat. # M0789), mouse monoclonal, clone PC10, HIER with 
pressure cooker (Decloaker, 30" at 121C, 21psi) in Target Retrieval buffer, 
45 min in primary antibody (current dilution is 1:200, but that varies with 
each new lot), 30 min in goat anti-Ms EnVision+/HRP, 15 min in AEC.  I use 
an autostainer, but it can be done manually with the same incubation times 
at RT.

This works for me on many mammalian species.
