http://test.tolobio.com/product_details/55.html WebTest the same volume of cDNA from each candidate control gene across the different experimental conditions in at least triplicate qPCR reactions. Assess the variability in measured Ct values for each control gene under your chosen conditions, by measuring their standard deviation (SD). 3.
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. If many data points are close to the mean, the standard deviation is small; if many data points are far from the mean, the standard … See more WebCt values apply the Low Value Tau calculation (i.e., the outlier is the lowest ranked replicate), if the putative outlier falls above the other replicate Ct values apply the ...
