Thank you for your question. This antibody has been previously cited for detection of PCNA in chicken samples. For IHC, you could use the unconjugated antibody, with an appropriate secondary antibody for detection, or the Biotin conjugated primary with an ABC Staining System, or the HRP conjugate for direct immunoperoxidase staining. Using the directly conjugated primary antibody can save you time and money on reagents. We do not have a preference for this particular antibody, and think you would be successful using either version of the antibody, depending on your preferences in your lab.
