Similar binding of ABP 980, trastuzumab (EU) and trastuzumab (US) to Fcγ receptors. Representative sensorgram overlays are shown for 2 lots of ABP 980 (red) and a single lot each of trastuzumab (US) (black) and trastuzumab (EU) (blue). (a) FcγRIa (b) FcγRIIa (131H) (c) FcγRIIb (d) FcγRIIIa (158 V) (e) FcγRIIIa (158F) (f). FcγRIIIb. Abbreviations: trastuzumab (EU) EU authorized trastuzumab, trastuzumab (US) FDA licensed trastuzumab.
