通用的高通量方法可以基于时空表型分离单细胞。解开表型的遗传和表观遗传决定因素对于理解和重新设计生物学至关重要,并且将受益于基于表型分离细胞的改进方法。在这里,我们报告SPOTlight,一个多功能的高通量技术,以分离单个酵母或人类细胞与独特的时空配置文件从异质群体。SPOTlight依赖于通过显微镜成像的视觉表型,对单个靶细胞的精确光学标记,以及通过荧光激活细胞分选来检索标记的细胞。为了说明SPOTlight基于时间特性筛选细胞的能力,我们选择开发一种光稳定的黄色荧光蛋白用于扩展成像实验。我们筛选了300万个表达诱变文库的细胞,并确定了一个明亮的新变体mGold,这是迄今为止报道的最耐光的黄色荧光蛋白。我们预计,SPOTlight的多功能性将有助于其部署,以破译生命规则,了解疾病,并设计新的分子和细胞。
Versatile high-throughput method can isolate single cells based on spatiotemporal phenotypes. Unraveling the genetic and epigenetic determinants of phenotypes is critical for understanding and re-engineering biology and would benefit from improved methods to separate cells based on phenotypes. Here, we report SPOTlight, a versatile high-throughput technique to isolate individual yeast or human cells with unique spatiotemporal profiles from heterogeneous populations. SPOTlight relies on imaging visual phenotypes by microscopy, precise optical tagging of single target cells, and retrieval of tagged cells by fluorescence-activated cell sorting. To illustrate SPOTlight’s ability to screen cells based on temporal properties, we chose to develop a photostable yellow fluorescent protein for extended imaging experiments. We screened 3 million cells expressing mutagenesis libraries and identified a bright new variant, mGold, that is the most photostable yellow fluorescent protein reported to date. We anticipate that the versatility of SPOTlight will facilitate its deployment to decipher the rules of life, understand diseases, and engineer new molecules and cells.
