High-sensitivity quantitative PCR platform.
Real-time PCR methods have become widely used within the past few years. However, real-time PCR is rarely used to study chronic diseases with low pathogen loads, presumably because of insufficient sensitivity. In this report, we developed an integrated nucleic acid isolation and real-time PCR platform that vastly improved the sensitivity of the quantitative detection of the intracellular bacter...
متن کاملNanoliter high throughput quantitative PCR
Understanding biological complexity arising from patterns of gene expression requires accurate and precise measurement of RNA levels across large numbers of genes simultaneously. Real time PCR (RT-PCR) in a microtiter plate is the preferred method for quantitative transcriptional analysis but scaling RT-PCR to higher throughputs in this fluidic format is intrinsically limited by cost and logist...
متن کاملIncreased sensitivity of one-tube, quantitative RT-PCR.
With the introduction of real-time, fluorescence-based 5′ nuclease PCR (3,4) and instruments such as the ABI PRISM 7700 (TaqMan) sequence detector (Applied Biosystems, Foster City, CA, USA), quantitative RT-PCR is now a widely accepted method for measuring gene expression levels. Quantitative RTPCR is a sensitive technique and is particularly useful for the analysis of samples containing limi...
متن کاملHigh-sensitivity PCR detection of parvovirus B19 in plasma.
Parvovirus B19 (B19) is a human pathogen transmitted to susceptible individuals via respiratory secretions and contaminated blood or blood products. B19 levels in pooled plasma of less than 10(4) genome equivalents/ml may not be infectious, while those greater than 10(7)/ml are capable of transmitting infection. A World Health Organization (WHO) B19 DNA international standard has been recently ...
متن کاملHigh sensitivity PCR assay in plastic micro reactors.
Small volume operation and rapid thermal cycling have been subjects of numerous reports in micro reactor chip development. Sensitivity aspects of the micro PCR reactor have not been studied in detail, however, despite the fact that detection of rare targets or trace genomic material from clinical and/or environmental samples has been a great challenge for microfluidic devices. In this study, a ...
