Succinimide and deamidaNon were detected for the studied samples on residues N144, N213, N154, N218 and N219. N213/N218/N219 and N144 succinimide levels were observed at consistent levels for the four DP batches and DS ranging from 0.96% to 1.17%. N144 and N154 deamidaNon showed comparable results for all the samples analysis with values between 0.15% and 0.34%. N218/N219 deamidaNon showed the highest variability between samples with values from 0.72 % for the DS and DP batch to 1.33% for DP batch 2, 3 and 4. The data is visualised in Figure .
