  • Performance Indicators

    To eliminate the different measurement scales used by the analytical method based on concentration levels and fluorescence levels [34], we divided the data of all concentrations by the highest concentration data and all fluorescence data by the average value of the maximum observed target quantity (F0), so that the average value of the maximum conc...

  • Indicator Evaluation

    In the supplementary information, the original amplification experiment data of the two data sets used in this study were obtained from Reference [28] after being processed into the readable format of the CqMAN system. We imported the data of these two data setsinto the CqMAN system to obtain the F0, Cq, and E calculated by the CqMAN, integrated th...

  • Biomarker Dataset Analysis

    The performance indicator values determined from the concentration series included in the measurement of the 20 genes are summarized in box-and-whisker plots. The boxes range from the 25th to the 75th percentile and are divided by the median; the whiskers are set at the 5th and 95th percentile (A) Bias in the slope level, which is based on the degr...

What does a low PCR efficiency mean?

PCR efficiency • When PCR efficiency is 100%, the amount of product doubles with each cycle • Lower efficiency means that the Cq is delayed and less product is made each cycle PCR efficiency E=100% lower lowest PCR efficiency • Can be expressed in three ways: 1)As a percentage: 0-100% 2)As a proportion: 0-1 3)As a fold increase: 1-2

What are the basic principles of qPCR?

The basic principles of qPCR are discussed on this page, and the mechanisms of the common detection chemistries are described in Quantitative PCR and Digital PCR Detection Methods. When performing qPCR, a fluorescent reporter dye is used as an indirect measure of the amount of nucleic acid present during each amplification cycle.

How does a threshold line affect CQ PCR efficiency?

Cycle threshold Placement of threshold line affects Cq PCR efficiency • When PCR efficiency is 100%, the amount of product doubles with each cycle • Lower efficiency means that the Cq is delayed and less product is made each cycle PCR efficiency E=100% lower lowest PCR efficiency

What is the difference between qPCR and conventional PCR?

Since the products are detected as the reaction proceeds, qPCR has a much wider dynamic range of analysis than conventional, end-point PCR; from a single copy to around 10 11 copies are detectable within a single run.
