Abstract
A real time Taq-Man PCR assay for detecting multiple serotypes of human papillomavirus (HPV) wherein the number of serotypes detected exceeds the number of colorimetric channels for detection. A biological sample is combined with three oligonucleotide primer/probe sets such that the probes and primers anneal to a target sequence. Each primer/probe set is at least preferential for a specific serotype of an organism. The first and second primer/probe sets are degenerate with respect to each other. The third primer/probe set is not degenerate with respect to the first and second primer/probe sets and discriminates for a third serotype. The third primer/probe set has a signal moiety that emits signal at a wavelength that is the same or different from the wavelength emitted by the signal moiety of the degenerate primer/probe set probes. The target sequences, if present, are amplified and detected.
