Fluorescence Activated Cell Sorting

The Fluorescence Activated Cell Sorting (FACS) Core provides researchers with a powerful method to study and purify cells for wide applications in immunology, cell biology and other fields of biology.

Flow Cytometry is a technology used to make fluorescent measurements of special fluorochromes bound to or made by various cells as they travel in single file through one or more laser lines while confined by a laminar fluid. Common applications involve immunolabeling of extracellular or intracellular proteins with fluorochrome-conjugated antibodies, reactive dyes or nucleic acid dyes. Fluorochromes are excited to emit various colors of light by the lasers. Data acquisition is achieved with specialized computer software directly interfaced with the cytometer.
