The use of luciferase reporter genes together with luminescence detection has enabled high frequency monitoring of molecular circadian clock function in living tissues. With the help of an intensified CCD camera combined with an inverted epifluorescence microscope, the authors have established a new imaging strategy that makes use of transgenic cell type-specific expression of fluorescent proteins to identify cells of interest for subsequent circadian luminescence recording at single-cell resolution.
荧光素酶报告基因与发光检测的结合使用,使得对活体组织中分子生物钟功能进行高频监测成为可能。借助与倒置落射荧光显微镜相结合的增强型电荷耦合器件相机,作者建立了一种新的成像策略,该策略利用荧光蛋白的转基因细胞类型特异性表达来识别感兴趣的细胞,以便随后以单细胞分辨率进行昼夜发光记录。
