摘要
We describe in detail a custom-built two-photon microscope based on a modified confocal scanhead (Olympus Fluoview) and mode-locked Ti:sapphire laser (Coherent Mira 900). This system has internal detectors as well as external whole-field detection and an electro-optical modulator for blanking the beam on flyback and effecting fast changes in excitation intensity. This microscope can be used in deep, scattering samples for quantitative measurements with a wide range of fluorophores (GFP, fura, calcium green, calcium orange, fluo-3, DiI, DiO, fluorescein, rhodamine), for fluorescent photobleaching recovery and for uncaging. Images obtained with this system can be deconvolved with the Estimation Maximization algorithm using the program XCOSM (freeware available at: http://www.ibc.wustl.edu/bcl/xcosm/).
