WebThe mAbs in this study have measured IgG pI in the range of 6–9, within the range reported by Kingbury et al. Citation 29 in their comprehensive studies of 59 therapeutic mAbs that included 43 FDA-approved products. The pI of a mAb is a molecular property highly affected by the variable region, but also moderately affected by the IgG subclass. WebDespite the therapeutic success of monoclonal antibodies (mAbs), early identification of developable mAb drug candidates with optimal manufacturability, stability, and delivery attributes remains elusive. Poor solution behavior, which manifests as high solution viscosity or opalescence, profoundly affects the developability of mAb drugs.
