From: Human papillomavirus-16 presence and physical status in lung carcinomas from Asia
HPV-16 is detected in lung carcinomas from Asia. DNA purified from lung carcinomas from Asian patients were amplified by PCR using A: generic primers flanking the HPV L1 region (65 bp) and B: specific primers flanking the HPV-16 E6 region (96 bp) and revealed by agarose gel electrophoresis and ethidium bromide staining. MW: 100 bp molecular weight marker; wells 1-7: positive clinical samples; wells 8-9: Negative and positive control (DNA from HPV-16 recombinant plasmid).
