Fig. 5From: Construction of an immunotoxin via site-specific conjugation of anti-Her2 IgG and engineered Pseudomonas exotoxin A(a) ADP-ribosylation of eEF-2. Wheat germ extract including eEF-2 was incubated with biotinylated NAD+ in the presence of PE24-AzF or trastuzumab-PE24, and then the reactions were analyzed by western blot using streptavidin-HRP conjugate. b Binding analysis of trastuzumab and trastuzumab-PE24 on Her2 antigen by ELISA. The analyses were done three times. The error bars represent one standard deviationBack to article page
