| 摘 要： | 本研究旨在提高基因转染的效率。试验使用聚乙烯亚胺(polyethylenimine,PEI)介导质粒pEGFP-N1转染NIH-3T3细胞,分为两组,分别进行一次转染和二次转染,于转染48h后在荧光倒置显微镜下观察。结果显示,部分细胞发出绿色荧光,二次转染组发绿色荧光的细胞明显多于一次转染组,且二次转染法可以明显提高基因的转染效率。

| Abstract: | The study aimed at improving gene transfection efficiency. We used PEI-mediated plasmid pEGFP-N1 to transfect NIH-3T3 cells in this study. NIH-3T3 Cells were divided into two groups to conduct one and two transfection，and observed under fluorescent inverted microscope at 48 h after transfection. The results showed that some cells emited green fluorescence, and green fluorescent cells in two transfection group were more than one transfection group. Calculated transfection efficiency to showed that two transfection method could significantly improve gene transfection efficiency. |
