摘要

A common method for calculating results from qPCR experiments is the comparative Ct method, also called the 2~(-ΔΔCt) method. However, several assumptions are included in the 2~(-ΔΔCt) method and standard statistical analyses are not directly applicable. Here, we describe a different method, the X_0 method, for result calculations and statistical analysis from qPCR experiments. The X_0 method differs from the 2~(-ΔΔCt) method by introducing a conversion of the exponentially related Ct values into linearly related X_0 values, which represent the amount of starting material in a qPCR experiment. Results calculated by the X_0 method are illustrated for qPCR experiments with technical and biological replicates, including procedures to calculate standard deviations. Incorporation of primer efficiencies in calculations by the X _0 method is also described. Altogether, the X_0 method constitutes a very simple and accurate alternative to the 2 ~(-ΔΔCt) method for result calculations from qPCR data.
