| Research Abstract |
The loop-mediate isothermal amplification method (LAMP) amplifies DNA with high specificity efficiency, and speed. However, the LAMP is insufficient for quantification of target DNA in comparison to the real-time PCR. In this study, we developed quantitative LAMP assay for HSV-1 and HSV-2 by Qprobe, which is quenched via electron transfer between the dye and guanine base at particular position. In singleplex reaction, the quantitative LAMPs amplified HSV DNA within 15min. The quantitative LAMP for HSV-1 and HSV-2 had high sensitivity and reproducible. However, it was impossible to determine an optimal condition for multiplex amplification. In addition, a new molecular method by using Qprobe was evaluated for screening of GCV resistant HHV-6B. The results of the new molecular method were consistent with those of the direct sequence. The sequence-specific DNA-RNA chimeric probe (cycling probe) is also appropriate method for the detection of SNP. The combination of LAMP and cycling probe might be good tool for quantitative analysis. As the first step, we developed quantitative assay combine real-time PCR with cycling probe to discriminate wild type and Oka-vaccine strain of VZV.
