That using thin-layer isoelectrofocusing elec-trophoresis technique, the electrophoregram of copper, zinc-superoxide dismutase (Cu, Zn-SOD) was analyzed showed the enzyme had three bands closing each other and being distributed in ,(?)H 4.78 to 4.95 region in the electrophoretic spect-um, and was different from ehat olother species.

超氧化物歧化酶(Superoxide Di Sinutase,SOD)足目前国内外研究较多的一种金属酶,它有3种类型:Cu、Zn—SOD、Mn—SOD,Fe—SOD,以Cu,Zn—SOD研究的较多。超氧化物歧化酶能歧化超氧阴离子,是生物体内一种重要的氧自由基清除剂。目前人们已经从动物、植物、酵母中提纯到SOD,并对其
