本文描述了一种手动酪胺信号放大(TSA)多重免疫荧光(mIF)结合图像分析和空间分析的方案。该方案可与福尔马林固定石蜡包埋(FFPE)切片一起使用,根据实验室中可用的玻片扫描仪,每张载玻片可染色两到六种抗原。

在我们的实验室,我们正在研究人类结直肠癌。其进展为转移性疾病及其对治疗(包括免疫疗法)的反应。我们正试图通过研究原发性和转移性疾病中的肿瘤免疫微环境和肿瘤内微生物组来寻找新的预测和预后生物标志物。

在我们的项目中,我们目前正在实施多种技术,例如RNA测序,全外显子组测序,TCR测序循环游离DNA分析,免疫荧光和荧光研究所杂交。目前,我们的主要挑战是将荧光研究所杂交染色与酪胺信号放大多重免疫荧光相结合,以研究微生物组与免疫细胞之间的相互作用。我们的方法稳健、可重现、易于使用且具有成本效益。

它可以在任何拥有荧光扫描仪的实验室中进行设置,并且该方法可以与任何市售IHC抗体一起使用,而不是通常针对受限抗原组进行优化的市售试剂盒。
