Capillary electrophoresis (CE) is a widely used technique in biosciences. Some of the main uses of CE include: DNA fingerprinting - After the DNA has been amplified, it can be separated by CE.Separation can be at a resolution of one base pair and individual nucleotides can be identified so allowing a high resolution map of the DNA to be created. One of the principal advantages of gel-filtration chromatography is that separation can be performed under conditions specifically designed to maintain the stability and activity of the molecule of interest without compromising resolution. Absence of a molecule - matrix binding step also prevents unnecessary damage to fragile molecules, ensuring that gel-filtration separations generally give high recoveries of …
