| Abstract: | Superoxide Dismutase(SOD) from garlic was purified with the metal chelate affinity chromatography(MCAC), using chitosan as substrate. The SOD was purified to homogeneous in one step affinity chromatography. Its specific activity was 1191U/mg and recover was 71%. The experiment demonstrated that SOD could resist the high temperature over 60℃for 1h. |
