Figure 11. (A) SEC-Static Light scattering data of mAb1 showing similar MW of monomer and a shoulder species observed in mAb-1. SEC QELS data of mAb1 showing: (B) native monomer species with expected hydrodynamic radius of 5.3 nM, and (C) later eluting shoulder species with one HC succinimide 105 with a smaller hydrodynamic radius of 4.2 nM.
