光激活、光转化和光控开关荧光蛋白

荧光蛋白（FP）如GFP、YFP或DsRed都是可视化观察活细胞中细胞组分的强大工具。尽管如此，目前仍然会有传统FP达到极限的情形发生。普通FP无法观察特定兴趣蛋白中专有、空间有限的蛋白质群体，因为它们在整个细胞中都有表达。此时，光激活、光转化和光控开关荧光蛋白就登上了舞台。荧光套件中的成员可以从非荧光状态激活，可以改变发射光谱，甚至可以逆转式地“开启和关闭”。借助这些“光学荧光笔”，研究人员可以…

共聚焦显微镜针孔效应

在操作共聚焦显微镜，或在讨论这种装置的特性和参数时，我们不可避免地提到针孔及其直径。这篇简短的文章是针对那些没有足够时间钻研共聚焦显微镜的理论和细节但又想了解针孔效应的用户们来解释针孔的意义。
