"WebThe efficiency of the PCR should be between 90–100% (−3.6 ≥ slope ≥ −3.3). If the efficiency is 100%, the CT values of the 10 fold dilution will be 3.3 cycles apart (there is a 2-fold change for each change in CT). If the slope is below –3.6, then the PCR has poor efficiency. Parameters that affect the efficiency of PCR " - Ct for qpcr
