Preparative gel electrophoresis: detection, excision, and elution of protein bands from unstained gels.
Methods are described for localizing proteins in unstained gels and accurately excising the regions containing them. A gel elutor, which is all glass with Lucite fittings, is also described. The elutor removes proteins from gels with a high yield and concentrates the protein in a small volume. The elutor is simple and very easy to use. A way is presented for avoiding the oxidation of methionine and cysteine during preparative electrophoresis.
