摘要:
为获得人乳铁蛋白的沙漠小球藻(Chlorella sp. GTD8A1)的表达系统和稳定的小球藻GTD8A1-hLF工程藻种,将人乳铁蛋白基因导入小球藻细胞中进行表达鉴定。以人血cDNA为模板,RT-PCR扩增得到人乳铁蛋白基因(GenBank登录号NM-002343.4),经KpnⅠ和XbaⅠ双酶切后,连接到植物表达载体pCAMBIA2300-35S-OCS中,获得重组质粒载体pCAMBIA2300-35S-hLF-OCS,将重组质粒电击转入GTD8A1中,通过菌落PCR鉴定后扩大培养,在DNA和RNA水平分析人乳铁蛋白基因的整合和转录,SDS-PAGE和Western Blot分析获得70 ku的目的蛋白;将转基因藻种(GTD8A1-hLF)在BBM培养基中进行培养周期优化。结果表明,重组人乳铁蛋白在沙漠小球藻细胞中表达成功;通过Elisa测其人乳铁蛋白表达量在20 d时达到最大,浓度为13.28 mg/L。
