- Flow cytometry
- Analysis of biological material by detection of the light-absorbing or fluorescing properties of cells or subcellular fractions such as chromosomes passing in a narrow stream through a laser beam. Flow cytometry can be used with automated sorting devices to sort successive droplets of the stream into different fractions depending on the fluorescence emitted by each droplet.
* * *flow cytometry n a technique for identifying and sorting cells and their components (as DNA) by staining with a fluorescent dye and detecting the fluorescence usu. by laser beam illuminationflow cytometer n
* * *a technique in which cells are tagged with a fluorescent dye and then directed single file through a laser beam. The intensity of fluorescence induced by the laser beam is proportional to the amount of DNA in the cells.
* * *a technique in which cells suspended in a fluid flow one at a time through a focus of exciting light, which is scattered in patterns characteristic to the cells and their components; they are often labeled with fluorescent markers so that light is first absorbed and then emitted at altered frequencies. A sensor detecting the scattered or emitted light measures the size and molecular characteristics of individual cells; tens of thousands of cells can be examined per minute and the data gathered are processed by computer.
