Quantitative microscopy is a powerful method for performing phenotypic screens from which image-based profiling can extract a wealth of information, termed profiles. These profiles can be used to elucidate the changes in cellular phenotypes across cell populations from different patient samples or following genetic or chemical perturbations. One such image-based profiling method is the Cell Painting assay, which provides morphological insight through the imaging of eight cellular compartments. Here, we examine the performance of the Cell Painting assay across multiple high-throughput microscope systems and find that all are compatible with this assay. Furthermore, we determine independently for each microscope system the best performing settings, providing those who wish to adopt this assay an ideal starting point for their own assays. We also explore the impact of microscopy setting changes in the Cell Painting assay and find that few dramatically reduce the quality of a Cell Painting profile, regardless of the microscope used.
定量显微镜是一种强大的方法,可以进行表型筛选,从基于图像的分析中提取大量信息,称为图谱。这些图谱可用于阐明来自不同患者样本或遗传或化学干扰后的细胞群体中细胞表型的变化。基于图像的分析方法之一是细胞染色分析,该方法通过对八个细胞区室的成像来提供形态学见解。在这里,我们检查了细胞染色分析在多个高通量显微镜系统中的性能,发现所有系统都与该分析兼容。此外,我们为每个显微镜系统独立确定了性能最佳的设置,为那些希望采用该分析的人提供了他们自己的分析的理想起点。我们还研究了显微镜设置变化对细胞染色分析的影响,发现无论使用哪种显微镜,很少有设置会显著降低细胞染色图谱的质量。
