Abstract： 目的:构建人MCHR2真核表达载体,转染HEK293细胞,建立稳定转染细胞系. 方法:采用PCR方法,以人胎脑cDNA文库为模板扩增人MCHR2基因的全长cDNA编码区序列,DNA重组技术将其定向插入到真核表达载体pcDNA3.1(+),经酶切和PCR鉴定后,脂质体转染法转染HEK293细胞,通过G418选择培养,建立稳定转染细胞系,RT-PCR,Western Blot及免疫荧光法检测MCHR2的表达. 结果:成功构建了pcDNA3.1-MCHR2真核表达载体并已稳定转入HEK293细胞,建立了稳定转染细胞系,成功地表达目的基因. 结论:稳定转染细胞系的建立和基因表达为进一步研究MCHR2的功能提供了良好的实验基础.
