Question

Quizplus · Accepted Answer

Fluorescence-activated cell sorter (FACS) is a specialized flow cytometry technique that allows cells to be separated according to their sizes, densities, and surface markers tagged by specific fluorescent antibodies. This is achieved by using a laser to excite the fluorescently labeled cells and detecting the emitted light to sort the cells into different tubes or wells. Western blotting, ELISA, FA test on a microscope slide, and DNA gel electrophoresis are not capable of separating cells based on their size or surface markers.
