A semi-quantitative real-time RT-PCR assay was designed to measure gonococcal pilin antigenic variation (SQ-PCR Av assay). This assay employs 17 hybridization probe sets that quantitate subpopulations of pilin transcripts carrying different silent pilin copy sequences and one set that detects total pilE transcript levels. Mixtures of a DNA standard carrying(More)
