> Robert,
I asked someone in our cytology section about your inquiry. What they do is spin down the specinen in a centrifuge, decant the liquid, add about four drops of "HistoGel" (specimen processing gel from Richard-Allen Scientific, 12 vials - 10 ml per vial, Reorder number HG-4000-012), respin the specimen and collect the gel button, put it into a tissue specimen bag before placing it into the cassette. I hope this will work for you.
