Table 3. Summary of key statistics after BestKeeper analysis.

Colonic HT-29 cells
	DICER1	MVK	PGK1	POLR2A	PPIA	RPLP0
s.d. [±Cq]	0.68	0.71	0.95	0.97	0.67	0.88
coeff. of corr. [r]	0.947	0.823	0.988	0.931	0.935	0.877
p-value	0.001	0.001	0.001	0.001	0.001	0.001
Power [x-fold]	1.77	1.79	2.23	2.30	1.72	1.97

The standard deviation (s.d.) corresponds to the individual gene stability and the coefficient of correlation, with its respective p-value, corresponds to how closely the candidate reference gene resembles the BestKeeper ideal normalisation factor after repeated pair-wise analysis. The power value is determined by regression analysis, using fold change (x-fold) as a reference point, and a smaller value indicates a better reference candidate. Values for genes eliminated in earlier stages of analysis are not shown.
