Chapter 30: Capillary Electrophoresis Homework: 30-3, 30-4, 30-5, 30-7, 30-8 A separation method that is based upon the differential rate of migration of charged species in an applied dc electric field. A method for separating anions and cations including large molecules such as DNA, RNA, and proteins.

Capillary Electrophoresis A little thing called the Human Genome was sequenced with CE. An Applied Biosystems 3700 instrument was used. Applied Biosystems was cofounded by CU Chemistry Professor Marvin Caruthers. CE is capable of resolving DNA strands that differ in length by a single base.

The Basis for Electrophoretic Separations Electromigration: Movement of ions toward an oppositely charged electrode. Electroosmosis: movement of entire fluid near wall of capillary in one direction!

The Basis for Electrophoretic Separations Migration: Movement of charged particles in an electric field. Migration rate: ν = μ e E μ e = Electrophoretic mobility (cm 2 V -1 s -1 ) E = Electric Field (V cm -1 ) The electrophoretic mobility is proportional to charge and inversely proportional to frictional drag forces.
