Flow cytometry fmh principle
WebThe basic principle of flow cytometry is the passage of cells in single file in front of a laser so they can be detected, counted and sorted. Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths. The fluorescence can then be measured to determine the amount and type of ... WebJan 28, 2024 · Principles of Flow Cytometry. Flow cytometry uses three basic scientific principles—fluid dynamics, optics, and electronics—to detect, count, and do cell sorting. This process solves two primary pain points: Consider that prokaryotic cells have diameters as small as 0.1 µm (micrometers, or 0.1 x 10-6 meters), and eukaryotic cells have ...
