摘要: 设计1对引物将口蹄疫病毒(foot and mouth disease virus, FMDV)VP1基因克隆到T载体上,通过Nde I和Xho I双酶切VP1基因和pET-28(a),在T4连接酶的作用下构建重组表达载体pET-28a-VP1;然后用EcoR I和Xho I双酶切VP1基因与pET-41(a),在T4连接酶的作用下构建重组表达载体pET-41a-VP1;然后将这2个新构建的载体分别通过热冲击法转化BL21(DE3),37 ℃不同IPTG浓度和32 ℃、0.01 mmol/L IPTG诱导表达,SDS-PAGE结果显示pET-28a-VP1的表达量高于pET-41a-VP1,在DTT和乙醇的作用下,二者均没有可溶性蛋白出现。

Abstract: The foot and mouth disease virus VP1 gene was amplified by PCR and cloned into T vector, pET-28a-VP1 was achieved through pET-28a and T vector, were dual-enzyme digested by NdeI and XhoI; pET-41a-VP1 was achieved through pET-41a and T vector, were dual-enzyme digested by EcoR I and XhoI, respectively. Then both pET-28a-VP1 and pET-41a-VP1 were transformed into BL21, respectively. When 37 ℃, different IPTG concentrations and 32 ℃, 0.01 mmol/L IPTG inducible expression, the results showed that protein yield of pET-28a-VP1 more than pET-41a-VP1, moreover status of protein was not effected by DTT and ethanol.
