Does anyone have a policy on what they can use for IHC control tissue? We use patient tissue but there is some disagreement as to how old the case should be. We never exhaust a patient block, however, we do prefer to use more recent tissues as to avoid any issues with antigenicity loss. Of course, we always check with a pathologist before cutting up patient tissue, but there are some pathologists that are ok using more recent cases and some who are not. What is everyone else doing in the clinical setting?
