Fluorescence-Activated Cell Sorting

Fluorescence-activated cell sorting (FACS) is a specific type of flow cytometric method. The use of this method has in the past decades increased exponentially in clinical laboratories and research laboratories. The FACS machine is a laser-based biophysical technology that measures multiple characteristics of individual cells in a stream of fluid. It can obtain both qualitative and quantitative information. The method is widely used in clinics and laboratories for cell counting, cell sorting, and biomarker detection. The modern FACS machine can be used for simultaneous detection of up to 20 different parameters and can efficiently separate the rare positive event from a large population.

The machine offers rapid detection of multiple characteristics of single cells. Very often, measured characteristics are cell size, DNA content, expression of cell ...
