AKTA chromatograms and HPLC-SEC chromatograms of elute fractions of MabSelect PrismA runs. AKTA chromatogram of the 5 CV gradient elution from pH 6.0 to pH 3.6 with a 15 CV hold at pH 3.6, with the point corresponding to pH 4.7 for FabscFv-KiH (a) as well as pH 4.3 and 4.1 for Fab2scFv-KiH (b) indicated with green arrows. The pH values indicated here represent the pH of each fraction measured by an external pH probe, with each fraction number indicated at the top of the chromatogram. HPLC-SEC chromatogram of FabscFv-KiH (c) and Fab2scFv-KiH (d) of each fraction of the eluates with absorbance values normalized to that of the monomeric peak, where each absorbance value was divided by the highest absorbance value of the monomeric peak. The likely hole–hole homodimeric mispaired products are indicated with*
