Real-time PCR, also called quantitative PCR or qPCR, can provide a simple and elegant method for determining the amount of a target sequence or gene that is present in a sample. Its very simplicity can sometimes lead to problems by overlooking some of the critical factors that make it work. See more To properly evaluate PCR efficiency, a minimum of 3 replicates and a minimum of 5 logs of template concentration are necessary. The reason for this suggested level of rigor is illustrated in Figure 6, which demonstrates … See more Another critical parameter to evaluating PCR efficiency is R2, which is a statistical term that indicates how good one value is at predicting another. When R2 is 1, the value of Y (Ct) can be used to accurately predict the value of … See more Any system capable of effectively amplifying and detecting one copy of starting template has achieved the ultimate level of sensitivity, regardless of the absolute value of … See more The standard deviation (square root of the variance) is the most common measure of precision.
