Fluorescence Microscopy & Cell Imaging

Microscopy is at the heart of understanding tissue architecture, cell structure and dynamics, as well as molecular function. Fluorescence microscopy is routinely used to determine spatial and topological information about cells and tissues. Sophisticated laser scanning microscopic instrumentation, ultra sensitive digital cameras and specialized fluorescence probes make it possible to visualize cellular events in real time down to the molecular level.
