Matrix assisted laser desorption ionization mass spectrometry imaging (MALDI MSI) is an emerging analytical technique, which generates spatially resolved proteomic and metabolomic images from tissue specimens. Conventional MALDI MSI processing and data acquisition can take over 30 min, limiting its clinical utility for intraoperative diagnostics. We present a rapid MALDI MSI method, completed under 5 min, including sample preparation and analysis, providing a workflow compatible with the clinical frozen section procedure.

用于手术病理学的快速MALDI质谱成像。

基质辅助激光解吸电离质谱成像(MALDI MSI)是一种新兴的分析技术,可从组织标本生成空间分辨的蛋白质组和代谢组学图像。传统的MALDI MSI处理和数据采集可能需要30分钟以上的时间,从而限制了其在术中诊断中的临床实用性。我们提出了一种快速的MALDI MSI方法,在5分钟内完成,包括样品制备和分析,提供了与临床冷冻切片程序兼容的工作流程。
