Quantitative PCR and RT-PCR in virology.
I n the last few years, molecular hybridization methods have been used extensively in basic and applied virology because of their technical flexibility and high specificity. Using these techniques, the detection of DNA and RNA viruses directly from clinical specimens, the analysis of the specific transcriptional activity of viral genes in vitro and in vivo, and the study of virus-host relations...
متن کاملGuidelines for quantitative rt-PCR.
Something I notice often in supervising new graduate students is their frustration with the irreproducibility of their biological data. For example, I am asked frequently ‘‘how many biological replicates do I need for qRT-PCR’’? The answer, of course, lies first with the students themselves. They need as many replicates as will persuade them of the validity of their observations. However, for m...
متن کاملQuantitative RT-PCR: pitfalls and potential.
Reverse transcription PCR (RT-PCR) represents a sensitive and powerful tool for analyzing RNA. While it has tremendous potential for quantitative applications, a comprehensive knowledge of its technical aspects is required. Successful quantitative RT-PCR involves correction for experimental variations in individual RT and PCR efficiencies. This review addresses the mathematics of RT-PCR, choice...
متن کاملQuantitative RT-PCR: limits and accuracy.
In this paper we determine the limits and accuracy of quantitative reverse transcription (RT)-PCR using a modification of the original protocol. The quantification of mRNA with this procedure requires a preliminary estimation of the target molecule (TM) concentration, established from experiments with an internal control molecule (ICM). A definitive quantification is then attained from serial d...
متن کاملQuantitative RT-PCR using a PCR-generated competitive internal standard.
One approach to quantitate RNA is the use of a known number of competitive internal standard molecules that are reverse-transcribed and subsequently co-amplified under the same reaction conditions as the target sequence (3). This technique, called competitive reverse transcription polymerase chain reaction (cRT-PCR) has been applied to monitor the level of hepatitis C virus (HCV) RNA in patient...
