引入小分子到显影果蝇胚胎提供了用于表征的新化合物,药物和毒素的生物活性,以及用于探测基本发育途径的巨大潜力。本文所述的方法概括了战胜自然障碍,这种做法,扩大了果蝇胚胎模型的实用步骤。
以下实验的总体目标是制备具有可渗透蛋壳的活果蝇胚胎,以测试引入的小分子药物或毒素的生物活性。这是通过首先用稀释的漂白剂处理发育阶段的胚胎以去除绒毛膜蛋壳层来实现的。第二步是用溶剂渗透胚胎,以耗尽阻塞小分子溶质的薄蜡质蛋壳层。
第三步是用药物或毒素和染料处理胚胎,以同时测量蛋壳的通透性并引入感兴趣的化合物。进一步发育后,胚胎可以直接成像或处理以进行免疫组织化学。最终,结果可以显示药物或毒素对组织发育的活性,这是通过使用免疫试剂或重要连接物的荧光显微镜确定的。
