Fluorescence-activated cell sorting (FACS) is a specialized type of flow cytometry. It sorts a heterogeneous mixture of biological cells into two or more containers, one cell at a time, based upon the specific light scattering and fluorescent characteristics of each cell and its attached antibodies. Fluorophores are attached to an antibody that recognizes a target feature on or in the cell and binds to it. Each fluorophore has a characteristic peak excitation and emission wavelength. FACS provide fast, objective and quantitative recording of fluorescent signals from individual cells as well as physical separation of cells of particular interest.
