One of the workhorse techniques widely utilized in the study of biological macromolecules (DNA, RNA, protein) is gel electrophoresis. Electrophoresis is the process of inducing the migration of charged particles under the influence of an electrical field or current. Gel electrophoresis combines the application of...
