WebHow flow cytometry works. Flow cytometers contain three main systems—fluidics, optics and electronics. The fluidics system funnels a sample of cells (e.g., a sample of human blood) into a single stream so that the cells pass through a laser beam one at a time. As each cell passes through the beam, it scatters light and may emit fluorescent light. WebThreshold: Degree to which a flow cytometer can distinguish particles dimly stained from a particle-free background. Usually used to distinguish populations on the basis of Molecules of Equivalent Fluorochrome (MEF). 2.
