Structure and in vitro characterization of CD25-ADC. (A) Structure and (B) in vitro characterization of CD25-ADC. (i) ELISA showing binding of anti-CD25 antibody PC61 to mouse recombinant CD25. (ii–iv) Flow cytometry measurement of PC61 and isotype-control antibody binding to Yac-1, MC38 and CT26 cells. (v–vii) Yac-1, MC38 and CT26 cells’ viability after exposure to CD25-ADC and isotype-ADC (and the naked pyrrolobenzodiazepine-dimer SG3199 in MC38 and CT26 cell lines). MFI, median fluorescence intensity; PABA, para amino benzoic acid.
