Rapid, Reproducible Real-Time Quantitative RT-PCR Using the iCycler iQ Real-Time PCR Detection System and iQ Supermix, Rev A

ere extremely reproducible: macula-enriched target transcript CT in the macula-derived samples was 19.9 0.2 cycles (n = 11), and 21.4 0.3 cycles (n = 11) in the periphery-derived samples (compare Figures 2, 3, and 4A). Here we have demonstrated that the use of iQ supermix to optimize reaction conditions allows the best consistency and reproducibility from experiment to experiment.
