ProteinElectrophoresis
DefinitionAmino acids, nucleotides, polypeptides, and other compounds in a colloidal state can be separated by the application of external voltages which cause charged colloid particles to move toward an electrode. This phenomenon is known as electrophoresis, from the Greek, "borne by electricity." This phenomenon of movement of electrically charged particles in a fluid under the influence of an electric fi......阅读全文
