Fluorescence microscopy is the method of choice for studying intracellular ***,its success depends on *** of specific and stable markers.A prominent example of markers that are rapidly gaining interest are nanobodies(Nbs.-15 kDa),which can be functionalized with bright and photostable organic *** to their relatively small size and high specificity,Nbs offer great potential for high-quality long-term subcellular imaging,but suffer from the fact that they cannot spontaneously cross the plasma membrane of live *** have recently discovered that laser-induced photoporation is well suited to deliver extrinsic labels to living cells without compromising their *** a laser-based technology,it is readily compatible with light microscopy and the typical cell recipients used for *** by these promising initial results,we demonstrate here for the first time successful long-term imaging of specific subcellular structures with labeled nanobodies in living *** illustrate this using Nbs that target GFP/YFP-protein constructs accessible in the cytoplasm,actin-bundling protein Fascin,and the histone H2A/H2B *** an efficiency of more than 80%labeled cells and minimal toxicity(-2%),photoporation proved to be an excellent intracellular delivery method for ***-lapse microscopy revealed that cell division rate and migration remained unaffected,confirming excellent cell viability and *** conclude that laser-induced photoporation labeled Nbs can be easily delivered into living cells,laying the foundation for further development of a broad range of Nbs with intracellular targets as a toolbox for long-term live-cell microscopy.
