In this article, we report the number of cyclin B1 proteins tagged with enhanced green fluorescent protein (eGFP) in fixed U‐2 OS cells across the cell cycle. We use a quantitative analysis of epifluorescence to determine the number of eGFP molecules in a nondestructive way, and integrated over the cell we find 104 to 105 molecules. Based on the measured number of eGFP tagged cyclin B1 proteins, knowledge of cyclin B1 dynamics through the cell cycle, and the cell morphology, we identify the stages of cells in the cell cycle. © 2020 The Authors.

使用绿色荧光蛋白标记和落射荧光对整个细胞周期中的 B1 细胞周期蛋白表达进行定量成像。

在本文中,我们报告了整个细胞周期中固定 U-2 OS 细胞中用增强型绿色荧光蛋白 (eGFP) 标记的细胞周期蛋白 B1 蛋白的数量。我们使用荧光定量分析以非破坏性方式确定 eGFP 分子的数量,并在细胞上整合我们发现 10 4到 10 5 个分子。根据测量的 eGFP 标记的细胞周期蛋白 B1 蛋白的数量、细胞周期中细胞周期蛋白 B1 动力学的知识以及细胞形态,我们确定了细胞周期中细胞的阶段。© 2020 作者。由 Wiley Periodicals LLC 出版的Cytometry Part A。代表国际细胞计量学促进会。
