Anti-CD59 antigen-binding Fc fragments (Fcabs) from initial selections of Fcab libraries: (a) HPLC-SEC chromatography of derived mAb2 molecules in native conditions (MWS: molecular weight standard); (b) ELISA with coated CD59; (c) Competition of biotinylated HuMax-20 (HX)-BER3 mAb2 with HX-BER1, HX-BER2 and HX-BER3; (d) Biolayer interferometry measurement of response to immobilized CD59: HX-BER1 to 3 were applied in 2-fold dilution steps starting from 1 µM. RX: rituximab, TRA: trastuzumab.
