Molecular analysis of EBV-positive and negative Non-Hodgkin lymphomas. (A) Nested-PCR EBV genotyping. Expected sizes of nested PCR products were 250 bp (type-1) and 300 bp (type-2), amplified from an 801 bp fragment obtained in the first PCR reaction. Lane 1: Type-1 positive control (Raji cell line); lanes 2–3: EBV-positive type-1 patients; lane 4: Type-2 positive control (BC1 cell line); lane 5: EBV-positive type-2 patient; lane 6: EBV negative patient; lane 7: negative control (Ramos cell line); lane 8: PCR control (without DNA). (B) DNA amplification testing by multiplex PCR of constitutive β-globin, β-actin and Glyceraldehide-3 phosphate dehydrogenase genes (from bottom to top) corresponding to patients and controls in A. 2.5% agarose gel stained with ethidium bromide. M: molecular weight marker (100 bp ladder).
