A Brief Introduction to Flow Cytometry
Dr. Malte Paulsen gives an introduction to flow cytometry with an excellent explanation of the basic principles governing the technique. He explains how fluid flow is used to focus a sample in a laser beam. Light from the laser is scattered by cells in the sample and the degree of scatter provides information about the cell’s optical density and other characteristics. In conventional flow cytometry, lasers are used primarily to excite fluorescent antibodies bound to specific cell types. A detector with different filters allows specific wavelengths to be dissected from the overall fluorescence. This signal can then be displayed in ways that provide the most information about the cell type of interest.
