Regression lines for several genes showing predicted regression lines and actual means over both experiments. The most stable and consistent control genes would have the lowest slope and closest fit to the regression line. UBQ (second from bottom) had the highest and TUA (top) the second highest stability indices in this experiment. CYP (third from bottom) had the lowest stability index. See Table 1 for descriptions of tissue samples.
