The human colon cancer LoVo cells were transfected by Lipofectamine 2000 with plasmid vector, and then selected for 4 weeks by G418. The expression of cerb-B1 mRNA was assessed by real time PCR and the protein of EGFR was assessed by Western blot method.

• 应用脂质体Lipofectamine2000转染人结肠癌LoVo细胞,转染成功后以G418筛选4周,实时荧光定量RT-PCR(RealTimeRT-PCR)检测cerb-B1基因的mRNA表达,Western-blot检测EGFR蛋白的表达。
