Abstract

The higher order structure of protein therapeutics can be interrogated with hydrogen/deuterium exchange mass spectrometry (HDX-MS). HDX-MS is now a widely used tool in the structural characterization of protein therapeutics. In this review, HDX-MS based workflows designed for protein therapeutic discovery and development processes are presented, focusing on the specific applications of epitope mapping for protein/drug interactions and biopharmaceutical comparability studies. Future trends in the application of HDX-MS in protein therapeutics characterization are also described.

摘要

蛋白质治疗药物的高级结构可以用氢/氘交换质谱(HDX-MS)来检测。HDX-MS 现在是蛋白质治疗药物结构特征描述的一种广泛应用的工具。在这篇综述中,我们展示了基于 HDX-MS 的工作流程在蛋白质治疗药物的发现和开发过程中的具体应用,重点是蛋白质/药物相互作用和生物仿制药可比性研究中的表位作图的特定应用。还描述了 HDX-MS 在蛋白质治疗药物特征描述中的应用的未来趋势。
