我们描述了一种专门为裂殖酵母(裂殖酵母)细胞的可逆固定化而设计的微流控装置,以促进活细胞的超分辨率显微镜。光活化定位显微镜(Palm)用于在活细胞内创建详细的超分辨率图像,在横向维度上的模式精度为>25纳米。新颖的流动设计将细胞捕获并保持在定义良好的阵列中,对正常生长动力学的影响最小。在荧光成像期间,细胞可以保持几个小时,并可以在设备内继续生长和分裂。
We describe a microfluidic device designed specifically for the reversible immobilisation of Schizosaccharomyces pombe (Fission Yeast) cells to facilitate live cell super-resolution microscopy. Photo-Activation Localisation Microscopy (PALM) is used to create detailed super-resolution images within living cells with a modal accuracy of >25 nm in the lateral dimensions. The novel flow design captures and holds cells in a well-defined array with minimal effect on the normal growth kinetics. Cells are held over several hours and can continue to grow and divide within the device during fluorescence imaging.
