The Microscopy & Imaging Shared Resource (MISR) provides instrumentation and expertise for light microscopy. Users incorporate a variety of imaging techniques into their studies including total internal reflection microscopy (TIRF), laser scanning and spinning disk confocal, and automated image acquisition for screening of multiwell samples. Applications include fluorescence resonance energy transmission (FRET), fluorescence lifetime intensity microscopy (FLIM) for FRET measurements, fluorescence recovery after photobleaching (FRAP), and other live imaging applications; multispectral emission imaging, and epifluorescence and brightfield time-lapse microscopy, microinjection, immuno-light microscopy and image analysis to study tumor cell biology.
