The migration of the molecule, known as electrophoretic mobility, depends on the type of polymer/gel used, its pore size, the voltage provided, running time and the surface to volume ratio. Basically, it is electrophoresis in a capillary, a narrow tube. A Brief History of Capillary Electrophoresis • 1937 – Tiselius develops moving boundary electrophoresis • 1967 – Hjertén uses rotating 3 mm i.d. Fluorescently labeled DNA samples are prepared for electrophoresis and loaded into the CE instrument. The capillary array is filled with polymer and placed into the sample wells. When the capillary array enters the wells, an electric current is formed, and the DNA fragments are moved electrokinetically into the capillaries. Capillary electrophoresis allows a rapid and accurate signature-based measurement for major chronic diseases diagnosis and monitoring and is routinely used in clinical laboratories for screening of serum and other fluids for protein abnormalities. Capillary electrophoresis (CE) is a powerful technique that allows for the detection of your target sequence using either fragment analysis or Sanger sequencing.
