Proportion of N-terminal peptide(s) quantified by triplicate analyses using mass spectrometry.

Light chain (LC); heavy chain (HC); signal peptide processing site: actual N-terminal (▼), erroneous N-terminal (▽); tryptic site (⬇). Signal peptide sequences are depicted in smaller font size.Erroneously processed N-terminal peptides >0.5% are presented individually, while those *Estimation of proportion of Remicade-HC N-terminal peptides may not be accurate as it relied on the quantification of peptides with one missed trypsin cleavage.Proportion of N-terminal peptide(s) quantified by triplicate analyses using mass spectrometry.
