*The flow cytometer is an instrument that directs cells in single file through a narrow chamber illuminated by a laser beam. As fluorescently-tagged cells pass through the laser beam, the fluorochrome is excited and emits light that is detected by a PMT-like detector

*This detector is capable of measuring the strength of emission, so it is possible to sort cells that are negative, slightly positive and highly positive for a specific antigen
