Capillary electrophoresis equipment employs a liquid buffer as the medium for separation instead of a gel. This permits the proteins and nucleic acids to move more naturally and spontaneously. The demand for this equipment is increasing because of its high efficiency and resolution abilities. Capillary electrophoresis has many advantages over gel electrophoresis, such as the requirement for a small amount of sample, direct protein detection with no staining, more accuracy, and improved automation.
