Hi All, Is anyone using this P16INK4A for IHC? I searched the archives and found some threads from 2009 with links that do not work for possible suppliers. I also found some for ELISA and Western Blot, and Flow Cytometry. Is this antibody used at all in FFPE tissue? Phyllis Thaxton HT(ASCP)QIHC DCH Regional Medical Center Tuscaloosa, AL
