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. NettetIntact mAb products have relatively long half lives and persist in circulation for long periods. Even fragments can persist in blood for several days. This can cause significant problems in detection of antibody responses due to the presence of mAb product in samples collected for antibody assessment. login online barclays
