Current LC-MS-based strategies for characterization and quantification of antibody-drug conjugates

更新时间:2023-05-28

【摘要】The past few years have witnessed enormous progresses in the development of antibody-drug conjugates(ADCs).Consequently,comprehensive analysis of ADCs in biological systems is critical in supporting discovery,development and evaluation of these agents.Liquid chromatography-mass spectrometry(LC-MS) has eme rged as a promising and versatile tool for ADC analysis across a wide range of scenarios,owing to its multiplexing ability,rapid method development,as well as the capability of analyzing a variety of targets ranging from small-molecule payloads to the intact protein with a high,molecular resolution.However,despite this tremendous potential,challenges persist due to the high complexity in both the ADC molecules and the related biological systems.This review summarizes the up-to-date LC-MS-based strategies in ADC analysis and discusses the challenges and opportunities in this rapidly-evolving field.
