Comparison performed at pH 7.4 to conform with the mAb profiling methodology. * Experimental aggregation propensity sourced from Jain et al.16 (maximum AC SINS scores = 29.6), † Experimental aggregation propensity sourced from by Jain et al.16 (low AC SINS scores ≤2.1) and determined in this work by the PEG aggregation assay, ‡ Experimental aggregation propensity sourced from Bethea et al.37 (stable at 110 mg/mL), and determined in this work by the PEG aggregation assay, # aggregation propensity determined in this work by the PEG aggregation assay.
