Results The serum antibody level reached to 0.71±0.08-0.77±0.06 after genetic vaccine pCD-HCV1(100 μg/mouse) were inoculated into the mice(n=12) three or four times while blank vector pCD-SRα1 could not induce the mice(n=8) to generate antibody response in same way.After the antibody levels in mice(n=8) immunized by pCD-HCV1 had ascended to peak value(0.71), there was no trend of descending during the following 18 weeks of detection(0.68±0.06-0.75±0.07). Specific fragment of HCV cDNA identified by polymerase chain reaction from DNA extracted from the muscles of the mice after pCD-HCV1 had beed inoculated three months.

结果 基因疫苗pCD-HCV1(100 μg/只)3-4次接种小鼠后(n=12)，血清抗体水平达0.71±0.08-0.77±0.06，空载体pCD-SRα1免疫鼠血清抗体阴性；免疫鼠(n=8)抗体水平达高峰后(0.71)，持续检测18周未见下降趋势(0.68±0.06-0.75±0.07)；pCD-HCV1免疫小鼠3个月后，用聚合酶链反应仍可从肌肉组织中扩增出特异性HCV cDNA片段；免疫鼠PBMC对HCV合成肽CP9、基因重组抗原C、E1刺激后均出现增殖反应，刺激指数分别为4.07±1.58、3.88±0.70和3.69±1.30，与pCD-SRα1免疫鼠相比，差异有显著性(P.001)。

Among these systems, the expression level of ZNF191(243—368) was increased in inclusion body system under a higher isopropylthio-β- D -galactoside concentration, but the non-target proteins were also increased more, which made its purification more difficult and the yield lower.
