摘要
目的 :构建合适的载体用于外源基因在巴斯德毕赤酵母中的正确分泌表达。方法 :利用PCR技术 ,对已有载体pPIC9K进行改造 :在多克隆位点处增加一个NaeⅠ酶切位点 ;去除卡那霉素抗性基因中的一个XhoⅠ酶切位点。结果和结论 :成功地构建了pMEN9K ,pMEX9K两个载体 。
Objective:To construct suitable vectors for the secretory expression of heterologous proteins in Pichia pastoris .Methods:A new unique restriction site Nae Ⅰ was added in multiple cloning sites and a restriction site Xho Ⅰ was eliminated in kanamycin resistance gene.Results and Conclusions:Two new vectors pMEN9K and pMEX9K derived from pPIC9K were successfully constructed,and they are suitable for the secretory expression of heterologous proteins.
