Degenerate "broad spectrum" HPV E1 primers detect HPV6, 11, 16 and 18. The E1 primer pair was used in a sybr green-based qPCR assay to determine the performance of this primer pair to detect and quantitate HPV. Reactions were performed using genomic clones of HPV6, 11, 16 or 18 as a standard curve that ranged from 1 × 106 to 1 × 102 copies and linear detection and quantitation of each amplicon was observed.
