Nuclear extracts concentration-dependent assay of multiple transcription factors. The solid red lines are the linear regression fits (ranging from 0.980 to 0.999) to the ∆Ct values for the 2 nM dsDNA probes with different protein-binding sites in the presence of increasing amounts of nuclear extracts. The final concentration ranges for HeLa cell nuclear extracts were 0.5 to 500 ng/ µl.
