Abstract:
The development of a multiplex polymerase chain reaction (PCR) method for rapid and accurate detection and typing of herpes simplex virus type 1 (HSV-1), and type-2 (HSV-2), cytomegalovirus (CMV) and Epstein-Barr virus (EBV) is very important for clinical diagnosis to allow the deliver of therapy as early as possible. Large scale amplifications by multiplex PCR of viral DNA can lower the cost and time for viral diagnosis. In this study, therefore sensitive quadruplex PCR was achieved by optimizing parameters such as primers, and 1.5 mM magnesium and 200 uM dNTPs concentrations. The concentrations of HSV-1, HSV-2, CMV and EBV primers were 0.5, 0.3, 0.25 and 0.25 pmoles, respectively. Optimal annealing temperature was 54 degrees C. Employing these conditions, we could detect 10 copies of reconstructed template plasmid DNA, which were cloned to vectors containing target sequences of viral DNA. PCR products of 271 bp for HSV-1, 231 bp for HSV-2, 368 bp for CMV, and 326 bp for EBV were separated on 5.0% polyacrylamide gel electrophoresis and confirmed by direct sequencing. The present study showed that the quadruplex PCR assay described herein has potential application in clinical diagnosis, when rapid, accurate detection and typing of viruses HSV-1, HSV-2, CMV or EBV are necessary.
