本协议描述了一个简单的方法来自动图像组织特异性的荧光斑马鱼胚胎。该协议是使用蔡司Axio上观察发展。 Z1的禅蓝2011软件，但该技术可以使用任何倒置显微镜电动载物台和显微镜控制软件，可以进行平铺，以创建复合图像调整。装备倒置显微镜具有机动阶段可以提供一个实用，更便宜的替代品购买专用设备，高内涵筛选。电动载物台的范围从几千元到数万美元，这取决于在舞台上的显微镜和?...

转基因斑马鱼已经开发了允许活动的直接可视化在信号通路，如成纤维细胞生长因子1，视黄酸2和雌激素3，在活的胚胎。这些工具使筛选任何干扰信号传导途径的化学品（如测定变化的荧光强度），或者该调制信号以组织特异性的方式（在荧光定位变化）4化学品。自动图像捕捉提高化学屏幕吞吐量大幅5,6。屏幕在现场斑马鱼自动检测荧光往往依赖于昂贵的专门设备。所谓高内涵筛选提供了高解析度，定量成像，但在使用专门的平板阅读器配备的共聚焦显微镜7,8的成本效益。该方法的目标是自动地检测组织特异性荧光在斑马鱼胚胎在使用标准的落射荧光显微镜用96孔板中。组织特异性的荧光可以使用这种技术来区分，可能是缺乏获得专门的平板阅读器或高内涵筛选设备实验室一个合理的方法。 在这个协议中，我们使用自动成像技术来检测组织特异性雌激素受体（ER）在活斑马鱼激动剂3天受精后（DPF）。转基因品系的Tg（5xERE：GFP）c262/c262包含5个串联的雌激素反应元件的DNA序列（ERE）的绿色荧光蛋白（GFP）的上游侧3。在没有配体时，预期结果通常无效。配体结合触发的构象变化，使受体结合ERE DNA和调节转录9。 5xERE：GFP的鱼可以用来筛选ER调节剂的化学库，可用于筛选环境水样的雌激素污染物。

semi-automated imaging of tissue-specific fluorescence in zebrafish embryos

斑马鱼的胚胎是一个强大的工具，用于小分子的大规模筛选。表达荧光报告蛋白的转基因斑马鱼经常被用来鉴定调节基因表达的化学品。化工屏幕，测定荧光活斑马鱼往往依赖于昂贵，专用设备高内涵筛选。我们描述了使用标准的落射荧光显微镜的过程与电动载物台自动图像斑马鱼胚胎和检测组织特异性的荧光。利用转基因斑马鱼是通过GFP的表达报道雌激素受体的活性，我们开发了一种半自动化的程序来筛选雌激素受体的配体激活的记者在一个组织特异性方式。在这段视频中，我们描述了在96孔板排列斑马鱼胚胎在24-48小时后受精（HPF），并补充说，结合雌激素受体的小分子过程。在72-96个高倍视野，每个图像以及从整个板被自动收集并手动检查组织特异性荧光。该协议表明，检测雌激素激活受体在心脏瓣膜，但不能在肝脏的能力。

图1示出的合成图像由一个96孔板的各孔中。每个复合图像由用5％的图像重叠59的单个图像。注意，这个活斑马鱼是随机取向于各孔中，但我们能够从肝脏区分荧光的心脏。明场图像作为参考来评估斑马鱼的方位和可视化形态异常（ 图1A和1C）是有用的。使用10x物镜自动成像被用于筛选化学物质，并确定哪些保证人工评估在更高的放大倍数， 图2示出了用于更?...
