Sequencing Learning Center . Capillary Electrophoresis Definition: These kind of separations are facilitated by the use of high voltages, which may generate electro-osmotic and electro-phoretic flow of buffer solutions and ionic species, respectively within the capillary. In other words, in order to distinguish various DNA molecules from each other, a separation step is required to pull the . Second, the enzyme should be able to withstand temperatures of 95-100C without denaturing and losing activity. For more information, see "Purifying PCR Products for . A molecule's electrophoretic mobility depends on its charge and how much it is attracted or repelled by the voltage as well as the frictional drag force that resists movement. Capillary electrophoresis is an analytical technique performed in a thin diameter glass tube that separates molecules and ions based on their mobility under the influence of an applied voltage.
