Mass spectrometry (MS) is an analytical technique that separates ionized molecules using differences in their mass, and can be used to determine the structure of the molecules. Matrix-assisted laser desorption/ionization (MALDI) is one of the most commonly used ionization methods for this procedure. A new technical method, imaging mass spectrometry (IMS), which is a two-dimensional MS, enables molecular imaging of tissue sections by the use of the MALDI-MS method. In this chapter, we briefly discuss available methods for analyzing glycolipids by IMS. We describe sample detection strategies, and also introduce a representative example of its research application.
质谱分析法(MS)是一种分析技术,它利用离子化分子的质量差异来分离这些分子,并且可用于确定分子的结构。基质辅助激光解吸/电离(MALDI)是此过程中最常用的电离方法之一。一种新的技术方法,即成像质谱分析法(IMS),它是一种二维质谱分析法,通过使用MALDI-MS方法能够对组织切片进行分子成像。在本章中,我们简要讨论通过IMS分析糖脂的可用方法。我们描述了样品检测策略,还介绍了其研究应用的一个代表性实例。
