In situ profiling of the tumor-immune microenvironment (TiME) requires the ability to co-localize and detect multiple proteins simultaneously. Imaging mass cytometry (IMC), using the Hyperion™ imaging system is a novel multiplex imaging modality that currently enables detection of up to 50 markers on fixed tissues at subcellular resolution and thus has the potential to inform both pre-clinical and clinical research by providing investigators with spatially resolved information about the TiME. Here we provide an overview of the IMC workflow from sample fixation to analysis, with a focus on multiplex panel design and tissue staining.
肿瘤免疫微环境(TiME)的原位分析需要同时共定位和检测多种蛋白质的能力。使用Hyperion™成像系统的成像质谱流式细胞术(IMC)是一种新型的多重成像技术,目前能够在亚细胞分辨率下检测固定组织上多达50种标志物,因此有潜力通过为研究人员提供有关TiME的空间分辨信息,为临床前和临床研究提供参考。在此,我们概述了从样本固定到分析的IMC工作流程,重点是多重检测板设计和组织染色。
