Figure 1. Polymerase chain reaction assay, amplification of HPV viral gene region E6/E7. HPV PCR E6/E7 assay: DNA from cervical samples was amplified by PCR (see methods). 1: negative control; 2: molecular weight ladder; 3: Generic positive control HPV-C001, amplicon of 630 pb; 4: HPV positive sample; 5–17: HPV negative samples. All samples shower the amplification of specific fragment to human beta-globin gene (4–17).
