Src l was an acidic cytolysin, which was reported forthe first time. The cDNA encoding the mature Src l was cloned into non-fusion expression vectorpBV220 and expressed successfully in E.coli DH5α in inclusion body. After washing anddenaturing-renaturing, the recombinant Src l protein was purified by Q Sepharose FastFlow ion exchange chromatograph and Phenyl Sepharose hydrophobic interactionchromatograph.

首先构建了Src I基因的非融合蛋白表达质粒pBV220-Src I，并成功地在原核细胞E.coli进行了重组表达，筛选出稳定表达的工程菌株DH5α，摸索了稳定表达的条件，摸索了包涵体的洗涤、变性和复性条件，摸索出了复性蛋白Src I的纯化工艺，纯化过程简单，经QSepharose Fast Flow阴离子交换层析和Phenyl Sepharose疏水层析两步纯化，就可获得了高纯度的重组蛋白样品(纯度达99％以上)，该纯化方法适合重组蛋白的大量纯化，为Src I的性质、结构和功能研究奠定了良好的基础。
