4. FLOW CYTOMETRY Fluorescence activated cell sorting (FACS) is a technology that allows simultaneous measurement of multiple physical and chemical characteristics of a single cell. These measurements are made on a per cell basis at routine rates of 500 to 70,000 cells per second in a moving stream.

49. CELL SORTING AS LIQUID IS EJECTED INTO AIR, IT WILL FORM DROPLETS BY VIBRATING THE NOZZLE AT A DEFINED FREQUENCY, THE SIZE OF THESE DROPLETS AND THE POSITION ALONG THE STREAM WHERE THEY FORM CAN BE CONTROLLED WITH PRECISION. A DROPLET CONTAINING A CELL IS APPLIED EITHER A NEGATIVE OR POSITIVE CHARGE AND SORTED BY PASSING THROUGH AN ELECTRIC FIELD.

51. CHROMOSOME ANALYSIS AND SORTING INDIVIDUAL CHROMOSOMES CAN BE ANALYZED IN FLOW AFTER APPROPRIATE PRESERVATION AND ISOLATION. THE MOST COMMON METHOD IS TO USE TWO DIFFERENT DNA DYES, ONE (HEOCHST 33258) THAT BINDS PREFERENTIALLY TO AT- RICH DNA AND ONE (CHROMOMYCIN A3) THAT BINDS PREFERENTIALLY TO GC-RICH DNA.
