In vitro studies demonstrated that whereas the binding affinity of NF-kappa B to the VCAM- NF-kappa B oligomer peaked at a GSH -to-oxidized glutathione ( GSSG ) ratio of approximately 200 and decreased at higher ratios, the binding to the E-selectin -NF-kappa B oligomer appeared relatively unaffected even at ratios > 400, i.e., those achieved in EC treated with 40 mM NAC .
