Quantification of vertical transmission of Murine polyoma virus by real-time quantitative PCR.
Pathogenesis studies of viral infections in vivo require sensitive assay methods. A sensitive and specific real-time quantitative PCR (RQ-PCR) assay was developed to detect Murine polyoma virus (MuPyV) DNA sequences. A quantitative assay to measure the single-copy murine wild-type p53 gene was developed to normalize viral gene copies to cell numbers. Both assays were sensitive over a seven-log ...
متن کاملComparison of droplet digital PCR and quantitative real-time PCR in mcrA-based methanogen community analysis
Two different quantitative PCR platforms, droplet digital PCR (dd-PCR) and quantitative real-time PCR (qPCR), were compared in a mcrA-based methanogen community assay that quantifies ten methanogen sub-groups. Both technologies exhibited similar PCR efficiencies over at least four orders of magnitude and the same lower limits of detection (8 copies μL-DNA extract-1). The mcrA-based methanogen c...
متن کاملRapid and accurate diagnosis of Foot-and-mouth disease virus by Real-time PCR in field samples
During 2010-2011, Real-time PCR procedure was used to detecting FMDV RNA on 147 epithelium samples from the field. In this survey, for Real-time PCR from 3D gene segment as conserve region selected for tracking all of seven serotypes FMDV. The assay detected the viral RNA in all serotypes of FMDV. The rRT-PCR specifically detected FMD virus in sample with greater sensitivity than our convention...
متن کاملComparison of droplet digital PCR to real-time PCR for quantitative detection of cytomegalovirus.
Quantitative real-time PCR (QRT-PCR) has been widely implemented for clinical viral load testing, but a lack of standardization and relatively poor precision have hindered its usefulness. Digital PCR offers highly precise, direct quantification without requiring a calibration curve. Performance characteristics of real-time PCR were compared to those of droplet digital PCR (ddPCR) for cytomegalo...
متن کاملQuantification of HEV RNA by Droplet Digital PCR
The sensitivity of real-time PCR for hepatitis E virus (HEV) RNA quantification differs greatly among techniques. Standardized tools that measure the real quantity of virus are needed. We assessed the performance of a reverse transcription droplet digital PCR (RT-ddPCR) assay that gives absolute quantities of HEV RNA. Analytical and clinical validation was done on HEV genotypes 1, 3 and 4, and ...
