     Hi, Mike:
     I am not sure whether it is the 'best procedure', it has been commonly 
     used though.  Please get the article by Hedley, DW., et al. Method for 
     analysis of cellular DNA content of paraffin-embedded pathological 
     material using flow cytometry. J. Histochem. Cytochem. 31: 1333-5, 
     It may also depend on what kind of tissue and cell you are using.  For 
     instance, we used to do DNA analysis by flow cytometry in 
     formalin-fixed, paraffin-embedded liver biopsy tissue using this 
     method with modifications. It was described in Mi, L-J., et al., DNA 
     ploidy analysis of hepatic preneoplastic and neoplastic lesions in 
     woodchucks experimentally infected with woodchuck hepatitis virus. 
     Hepatology, 20: 21-29, 1994.
     If you have more questions, I would be glad to be of further 
     Good luck.
