Ct levels of qRT-PCR, used for validation of candidate RFX regulators by siRNA knockdown. Individual Ct levels with automatic threshold obtained on an AB7500 Fast machine for SP2 and ESR1 as candidate RFX regulators and their respective test siRNA and scrambled (Scr) control siRNA knockdown data on RFX genes (RFX1, RFX2, RFX3, RFX5, RFX7) and the two reference genes (HPRT1, HSPCB).
