Abstract:
目的:制备嵌合结肠癌新抗原Adpgk的乙肝病毒核心抗原(HBcAg)病毒样颗粒(VLP)。方法:通过重叠PCR将新抗原编码序列插入截短型HBcAg(1~149 aa)第78、79位氨基酸编码序列之间,并将融合基因克隆至原核表达载体pET-22b(+),转化大肠杆菌BL21(DE3),经IPTG诱导表达后,利用亲和层析与超滤管纯化浓缩目的蛋白,通过Western印迹、粒径分析与透射电镜成像鉴定嵌合病毒样颗粒。结果:构建了pET-22b(+)重组表达载体并转入大肠杆菌BL21(DE3),SDS-PAGE结果显示在30℃经1 mmol/L IPTG诱导5 h即可获得高浓度的可溶性蛋白,通过亲和层析与...
