IgG antibodies from IFX-treated patient sera bind stronger to IFX epitopes than serum IgG from untreated healthy controls. Mean signal intensity of antibody-binding of IFX-treated patient serum and serum from untreated healthy controls to identified IFX epitopes (Fig. 2). Results of three independent epitope mapping experiments, each performed in duplicate, are shown. AU, arbitrary units
