Functional performance of universal RNA controls for real time qRT-PCR assays. Robust calibration control genes of MSG, CAB, RBS1, and ACTB at 0.1, 1, 10, and 1,000 pg over 80 individual 96-well reaction plates for Saccharomyces cerevisiae NRRL Y-50316 and NRRL Y-50049 treated with 8% (v/v) ethanol demonstrated highly fitted linear relationship between the mRNA input (log pg) and PCR cycle numbers (Ct) by a master equation for assays on ABI 7500 real time PCR System. Standard deviation of the slope and the intercept of the master equation based on 80 individual standard curves under varied experimental conditions was 0.0458 and 0.0966, respectively.
