中文摘要:
      在重组人IL-2(hIL-2)大肠杆菌高效表达的基础上,为了构建hIL-2与别的目的蛋白的嵌合分子,我们利用点突变PCR方法去除IL-2cDNA表达克隆的终止密码,并构建成hIL-2嵌合重组蛋白表达克隆,在大肠杆菌中表达的IL-2嵌合重组蛋白具有天然IL-2分子的生物活性。本文结果表明点突变PCR去除cDNA终止密码的方法效率高、快速、简便。
英文摘要:
      On the basis of over-expression of recombinant hIL-2 in E. coli,in order to construct multifunction chimeric molecules of IL-2 and other interest proteins,we deleted the stop codon of hIL-2cDNA expression clone through site mutation directed by PCR. The hIL-2 cDNA without stop codon was recombined with expression vector pKPL,constructed into expression clone pKPL-mhIL-2, which could over-expressed a chimeric recombinant protein of IL-2.The results here showed that the side mutation PCR method was rapid, convenient and high efficient for deleting stop codon of cDNA.
