The results are as follows: 37℃ is the most favorable temperature for induction expression of SUMO-hEGF in BL21, 5.0g/L the most best concentration of arabinose, and 4h the best time for induction expression. Meanwhile, the quantity of expression is around 20.2%. The conclusion that hEGF is the purified protein is verified by Western blotting. It is a good foundation for the development of hEGF genetic medicine.

结果表明： SUMO-hEGF在BL21中的最佳诱导表达温度为37℃、诱导剂阿拉伯糖的最佳浓度为5.0g/L、最佳诱导表达时间为4h，表达量约为20.2%；Western blot 分析证实，纯化后的蛋白是hEGF，为进一步开发hEGF基因工程药物奠定了基础。
