Flow Cytometry

Flow cytometry is a technique for rapidly analyzing large numbers of animal cells using light-scattering, fluorescence, and absorbance measurements. (1) Cells are drawn in liquid buffer under pressure into a (2) focused, single file stream that flows across the path of a laser beam which excites the dye, causing it to (3) emit light wavelengths that are (4) detected and (5) displayed as multiparametric data.
