摘要 从海洋双RNA病毒(MABV)基因组中克隆到VP5基因,将其连接到6×His融合表达载体pET-28a(+)上,在大肠杆菌中表达,并对其表达条件进行了优化。研究结果表明,在温度为28℃、IPTG浓度为0.1 mmol.L-1时,表达的融合蛋白相对最高,占细菌总蛋白的7.3%。 VP5 gene from MABV genome was amplified by RT-PCR, and was cloned into the 6×His fusion expression vector pET-28a (+), then expressed in Escherichia coll. The results showed that the expression level of the fusion protein was 7.3% of the total bacterial proteins under the optimized conditions, at temperature for 28℃ ,IPTG eoncentration for 0.1 mmol- L-l.
