Hi Colleen,
    Thanks for the info regarding the cytokeratin. How would you deal with
antibodies requiring different pretreatment (e.g. PK and HIER)? Also is
there any documentation for this mixing. I dont doubt you, I would just like
to have a reference to point out to management and doctors so they dont fear
the inquisition ... (inspectors).
