Abstract

High resolution fluorescent speckle microscopy (FSM) and green fluorescent protein (GFP) imaging in living cells can require image recording at low densities of fluorophores (10 or less/resolvable unit) with low light excitation to prevent photobleaching. This needs efficient optical components, a high quantum efficiency detector, and a digital image acquisition and display system for time-lapse recording of multiple channels. Recently, Shinya and Ted Inoue have described the advantages of the Yokogawa CSU-10 spinning-disk confocal scanning unit for obtaining high quality fluorescent images with brief exposures and low fluorescence bleaching. Based on their findings, we have combined the CSU-10 unit with a high sensitivity pan-chromatic CCD camera to facilitate high spatial and temporal resolution imaging of fluorescence in living cells. in addition, the high signal-to-noise in images obtained with this instrument provides the opportunity to obtain 3-D views of extraordinary resolution and image quality after iterative constrained de-convolution.

Our imaging system is constructed around a Nikon TE300 inverted microscope equipped with either a 60X or 100X Plan Apochromat objective, and standard epi-fluorescence optics for visual inspection of the specimen to locate cells for recording.
