Figure 5From: Isolation, characterization and molecular cloning of Duplex-Specific Nuclease from the hepatopancreas of the Kamchatka crabDSN activity against high molecular weigh ss and ds DNA. Agarose gel electrophoresis of M13 and lambda phage DNA before and after treatment for 10 min with 2 units of DSN at 70°C. Lanes: 1, M13 phage DNA treated with DSN; 2, lambda phage DNA treated with DSN; 3, mixture of M13 phage and lambda phage DNA treated with DSN; 4, untreated M13 phage DNA; 5, untreated lambda phage DNA; 6, untreated mixture of M13 phage and lambda phage DNA; m, 1-kb ladder (SibEnzyme).Back to article page
