Figure S1. Amplification of HPV positive and negative cell line genomic DNA by Touchdown PCR using BS GP5+/6+ primers. A dilution series of an HPV positive cell line (HeLa), HPV negative (HEK293) and HPV-status unknown cell lines were amplified by touchdown PCR with both HPV primer sets and a globin primer pair, and run on 1.5% agarose gels. Figure S2. Touchdown PCR from swab cell lysate, (A): Lane 1.- Lane 4 HPV positive control with input DNA 1 ng, 0.1 ng, 0.01 ng and 0.001 ng; Lane 5. HPV negative control (cell line); Lane 6. no template control. Lane 7 to Lane 16 indicate unknown swab samples. M indicate the DNA ladder marker. Touchdown PCR from HPV positive swabs by Hybribio Assay (B): Lane 1. – Lane 18 are swab cell lysate; Lane 19. HPV positive control (cell line); Lane 20. HPV negative control (cell line); Lane 21. no template control. The samples were amplified with the BSGP5+/6+ primers. (DOCX 2548 kb
