An immobilized pH gradient can be used in a two-dimensional form of this technique. Isoelectric focusing in this technique can be subject to cathodic drift. Denaturation of proteins to create (10[1])a uniform negative charge in this technique can be accomplished using detergents like SDS. SYBR (“cyber”) Gold is an intercalating agent used in this technique that is less toxic than traditional dyes. The size of molecules is inversely proportional to the migration rate in this technique. Acrylamide and agarose matrices are used in two forms of this technique. For 10 points, identify this laboratory technique that uses an applied electric field (-5[1])to separate biomolecules on a gel. (10[1])■END■
