AP-PCR fingerprint patterns of fresh frozen and formalin fixed, paraffin wax embedded blocks of two segments (A and B) of non-cirrhotic liver from a single patient. Identical profiles were observed on amplification of DNA from microdissected samples at different levels of the frozen blocks (F1 and F2) and paraffin wax blocks (P1 and P2). Similar results were obtained on amplification of various concentrations (a: 50 ng; b: 100 ng; c: 200 ng; d: 400 ng) of template DNA from each of the paraffin wax blocks.
