objective: to achieve the soluble expression of mn-sod gene in e.coli and assay the enzyme activity of the expressed product. methods: the coding region of superoxide dismutase was amplified using pcr method from the e.coli genome. the pcr product was cloned into puc19-t vector and sequenced.in addition,the cloned coding region of mn-sod was inserted into the expression vector pet-28a to form the recombinant plasmid pet-28a-mn-sod and was then transformed into e.coli bl21 for expression.

超氧化物歧化酶(superoxide dismutase，sod)是细胞体内歧化超氧阴离子自由基(o-2)的一个抗氧化酶，按其结合的金属性离子根据其中金属辅基的不同可分为4类：cu/zn-sod、mn-sod、fe-sod和ni-sod，它们通过催化超氧阴离子自由基0-2发生歧化反应，达到清除o-2的效果，具有防御氧毒性、增强机体抗辐射损伤能力、防衰老以及治疗某些肿瘤、炎症、自身免疫疾病等功效，广受国内外科研工作者的关注和重视[1]。
