To correct for non-specific DNA-binding, we determined, for each protein, a background level of non-specific binding corresponding to the observed abundance from a time-point at which the factor is known to be absent from origins.
Second, microarray analyses generally operate above a low background level of non-specific and off-target probe-array binding that can complicate the analysis of low-abundance molecular species (particular in cases where a related highly abundant product is present).
