After excitation with a laser, cells can scatter and emit light in different ways. This depends on their size, granularity, GFP-expression or other characteristics. In a flow cytometer, a stream of fluid containing cells passes through a laser beam. The scattered and emitted light is picked up by a detector. In this way cells can be counted and analyzed, based on one or more properties. Flow cytometry can also be combined with cell sorting.
