Nettet1. jun. 2024 · In this paper, unpaired cysteines observed in a therapeutic antibody (mAb1) were thoroughly studied by Liquid Chromatography-Mass Spectrometry (LC-MS) methods at the intact mAb, domain, and peptide levels. Three cysteine variants were observed at the intact mAb level with each variant containing two unpaired cysteines. NettetFigure 1 shows the deconvoluted mass spectrum of the intact mAb, with and without oxidative modification. Analysis of the deconvoluted spectrum clearly shows the broad peak for the oxidatively modified protein implying a different degree of oxidation.
