Figure 1: HPV detection assay. This figure shows the electrophotetic profile of 12 representative cases assayed by nested PCR for the detection of HPV L1. Cases 2, 4, 5, 6, 8, and 10 are positive as demonstrated by the presence of the amplicon generated by the GP 5+/6+ primer pair. Lane M is the molecular size marker; lanes 13 and 14 were HPV positive and water controls, respectively.
