In this chapter, we describe an LC-fluorescence (FLR)/MS-based method for released N-glycan analysis in the development of biotherapeutic proteins. The method includes enzymatic release and labeling of N-glycans with a signal-enhancing tag, LC-MS data collection, and data interpretation. Using the given protocol, up to 24 glycan samples can be prepared within 1 h, while the LC-FLR/MS data can be collected and analyzed using an established data processing method in a semi-automated manner.
在本章中,我们描述了一种基于 LC-荧光(FLR)/MS 的方法,用于在生物治疗蛋白的开发中分析释放的 N-聚糖。该方法包括用信号增强标签进行酶促释放和标记 N-聚糖、LC-MS 数据采集以及数据解释。使用给定的方案,在 1 小时内可以制备多达 24 个聚糖样品,而 LC-FLR/MS 数据可以使用半自动化的既定数据处理方法进行收集和分析。
