AP-PCR analysis of primary and satellite hepatocellular carcinoma (HCC) nodules. Autoradiograms of polyacrylamide gel electrophoresis of ³³P-labelled DNA fragments amplified by AP-PCR. Genomic DNA from each sample was amplified with the AR3 (A) and ZF3 (B) arbitrary primers. S1, S2, and S3 represent the three different sectors in the same primary HCC nodule of patient Sc. N, 1-3, and A-E represent non-tumour tissue, three different sectors of primary, and five satellite HCC lesions of patient Go, respectively. Size of bands (in base pairs) is indicated on the right.
