About Us

The Flow Cytometry & Confocal Microscopy Facility provides investigators with access to sophisticated instruments designed to detect and measure fluorescent light emission. The flow cytometers distinguish cells or particles based on size, internal complexity, and fluorescent signals. Cells or particles can also be sorted to obtain pure populations for further analysis or subsequent culture. Available imaging techniques include widefield, laser scanning confocal, spinning disk confocal, TIRF, and multiphoton confocal microscopy.
