Figure 1 HPV-positive tissues using a PCR-based ELISA assay. Agarose gel electrophoresis demonstrating specific DNA fragments, which were positively detected in several tissues. Fragments include the beta-globin internal control gene and the 450-bp HPV L1 gene fragment (M = marker). Patient numbers and tissue types are indicated: E = endometrium; En = endometriosis; P = peritoneum. The L1-positive control DNA is included in the kit. All PCR fragments were also analyzed for ELISA for further HPV typing; for example, patient 14, a CxCa, was HPV16 positive; endometriosis from patient 8 was HPV medium risk; endometrium tissue from patient 6 was HPV16, whereas peritoneum from the same patient was negative for HPV (Tables 2 and 3).
