Fluorescence-Activated Cell Sorting

Fluorescence-Activated Cell Sorting (FACS) is a laboratory technique used to separate and analyze cells based on their characteristics. Cells are marked with fluorescent dyes that attach to specific proteins on their surfaces. When passed through a laser, the cells emit light, allowing scientists to identify them. FACS sorts these cells by directing them into different containers according to their fluorescence and other properties. This technology is useful in research and medicine, enabling detailed study of cell populations, such as identifying cancer cells or studying immune responses.
