tokens: Electrophoretic mobility supershift assays determine that members of the NF-kappa B /Rel family of transcription factors can bind to this site in vitro and that DNA-binding complexes that contain p50 , p52 , p65 , and cRel correlate with positive regulation whereas the presence of p50 correlates with negative regulation .
