Fig. 2. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the ginseng polyphenol oxidase (PPO) resolved by carboxymethyl-Sepharose chromatography. The gel was stained for proteins with Coomassie blue. Lane 1, molecular weight markers; lane 2, dissolved acetone pellet; lanes 3 to 5, flow-though fractions (PPO 1); lanes 6 to 8, eluted fractions with 0.5 M NaCl (PPO 2).
