Single-molecule fluorescence microscopy enables unrivaled sub-cellular quantitation of genomically encoded fusions of native proteins with fluorescent protein reporters. Fluorescent proteins must undergo maturation after expression before they become photoactive. Maturation effects must be quantified during single-molecule analysis. Here we present a method to characterise maturation of GFP and mCherry genetic protein fusions in budding yeast .
单分子荧光显微镜能够对天然蛋白质与荧光蛋白报告基因的基因组编码融合体进行无与伦比的亚细胞定量分析。荧光蛋白在表达后必须经历成熟过程才能变得具有光活性。在单分子分析过程中必须对成熟效应进行量化。在此,我们提出一种在芽殖酵母中表征绿色荧光蛋白(GFP)和单体红色荧光蛋白(mCherry)基因蛋白融合体成熟过程的方法。
