XGFR* mediated inhibition of A549 and RD-ES cell proliferation. (A) A549 and (B) RD-ES tumor cells were seeded in poly-HEMA coated plates with increasing concentrations of bispecific antibodies XGFR and XGFR* or parental control antibody mixture R1507/GA201 and incubated for 7 d. Cell viability was measured by luminescence after addition of CellTiter Glo reagent. Titration curves in the indicated concentration range and IC50 values are depicted in the table. At least 2 independent data sets with comparable results were obtained.
