A novel fluorescence polarization based assay for 14 human papillomavirus genotypes in clinical samples.
A specific and practical method was developed for high throughput 14 human papillomavirus (HPV) genotypes assay in clinical samples by a single PCR. GP5+/6+ polymerase chain reaction (PCR) system was used to amplify HPV DNA in 1127 samples. The PCR product was assayed by AcycloPrime reaction with fluorescence polarization (FP). Fourteen HPV genotypes specific sequence primers designed within GP5+/GP6+ amplification polymorphism regions of L1 genes for corresponding HPV genotypes were annealed with the type specific PCR products and special fluorescent terminator was added to the end of the primer under direction of the PCR products. AcycloPrime-FP analysis showed specific anneal and incorporation without any cross-reaction. The types detected with FP showed an excellent overall agreement with sequence when the individual monotype results were taken into account. The proposed method could detect more than one type of HPV infection, but the sequence method was limited. AcycloPrime-FP could reach the detection level: 100 ag for representative phylogenetically distant HPV genotypes: HPV6, 18, 31, 39, 42, 51 and 58. The results of AcycloPrime-FP showed excellent reproducibility. The proposed method allowed an economical detection of HPV genotypes without any use of labeled probe. It is expected to be an extremely useful tool for HPV genotypes screening.
