Splet23. nov. 2016 · Proper adjustment of threshold line is actually based on the baseline signals of your reaction and this is very important for getting a valid corresponding Ct. Usually we run the experiment by... SpletC t (threshold cycle) is the intersection between an amplification curve and a threshold line (Figure 1B). It is a relative measure of the concentration of target in the PCR reaction. …

SpletSetting. Recommendation. Threshold. Enter a value for the threshold so that the threshold is: Above the background. Below the plateau and linear phases of the amplification curve. … SpletThe Cp is then the intersection of the regression line through these points with the threshold. The "single threshold" method is better if the curves do not exhibit a clear log-linear phase...
