摘要: 为探索猪圆环病毒Ⅱ型(PCVⅡ) ORF2基因的高效表达,将ORF2基因整合到酵母表达载体pPICZαC中,构建重组质粒pPICZαC-ORF2,通过SacⅠ酶切线性化,经电穿孔法转到毕赤酵母菌SMD1168。经ZeocinTM抗性筛选得到转化子,通过SDS-PAGE分析和Western blotting鉴定,结果表明衣壳蛋白在酵母菌中成功分泌表达。

Abstract: In order to research for high-level expression of porcine circovirus type 2(PCVⅡ) ORF2 gene, the ORF2 gene of PCVⅡ was cloned into the genome of the pPICZαC expression vector to construct the recombinant plasmid pPICZαC-ORF2, and the resultant plasmid digested by SacⅠ was intergraded into the genome of P. pastoris expression strain SMD1168 by electroporation. The transformants were selected with zeocin, and the results of SDS-PAGE and Western blotting showed the capsid protein of PCVⅡ was secretory expressed successfully.
