摘要 荧光蛋白在特异组织和器官表达的转基因斑马鱼已经在发育生物学和疾病模型研究中得到了广泛的应用。这些转基因系有助于追踪和分析数量较少的细胞群。但是如果要分离得到这些细胞来定量分析mRNA或蛋白质的表达情况比较困难。利用流式细胞仪分选这些荧光标记细胞是一种解决办法。此方法在不同的实验室中被广泛地应用,也有相关流程的介绍。但是流程一般较为繁琐,操作比较困难。该文以从转基因斑马鱼Tg(Kdrl:EGFP)中分选绿色荧光蛋白阳性的血管内皮细胞为例,介绍利用流式细胞仪分选转基因斑马鱼荧光标记细胞的实验流程和技术要点。该文作者在前人工作的基础上结合大量的实验经验,发展并优化了一套操作简便、效率较高的流程来分选这些细胞,在此做详细的介绍给大家以供参考。 The florescence proteins are used to specifically label organs, tissues or cell types in transgenic zebrafish reporter lines, which are extensively applied in developmental biology and disease modeling. They allow us to follow the several-labeled cells in vivo. In this paper, we introduced the procedure to sort the florescence positive cells in transgenic zebrafish embryo by fluorescence-activated cell sorting (FACs). Based on our experience of several experimental tests, this procedure was optimized to be very efficient and easy to handle.
