Purity analysis of reduced mAb

	Feed strategy 4		Feed strategy 5		Feed strategy 6		Feed strategy 7
	% Light	% Heavy	% Light	% Heavy	% Light	% Heavy	% Light	% Heavy
Peak 1	32.3 ± 0.6	66.2 ± 0.6	32.3 ± 0.6	65.9 ± 0.3	32.3 ± 0.5	66.5 ± 0.5	32.2 ± 0.5	66.4 ± 0.4
Peak 2	33 ± 1	37.1 ± 05	—	—	32.4 ± 0.7	46.4 ± 0.5	—	—

Note: The average apparent size of the light chain is ~29 kDa and the heavy chain is ~67 kDa. Peak areas were determined using GXII reviewer and represent the mean of three technical replicates on a mass basis. Error bars represent ±1 SD of the mean.
