[Reuel Cornelia]

Would you know a  techniqe to confirm cell viability in paraffin embedded tissue?  Propidium and methylene blue staining are used in cell culturing to detect cell viability.  Is there similar technique for detecting cell viability in tissue?
This question was asked by our research director, Can you please share your opinion on this and if there is chemical test to detect vaibility of cells in a paraffin tissue?
