UHR-ESI-QTOF mass spectrometry of (A) the mAb1 derived 1+1 and (B) mAb5 derived 2+1 CrossMabs digested with GingisKHAN™. Undigested and single-digested bispecific antibodies could not be detected in the deconvoluted spectra. The mass denoted a:50012 Da (B) was identified as the non-glycosylated Fc (expected average mass: 50012 Da). Expected average and determined (bold) masses of the Fabs are stated in parentheses.
