摘要: 试验旨在研究脂质体介导基因转染水牛肾脏成纤维细胞时如何获得较高的转染效率。本研究将以绿色荧光蛋白基因为标记基因,利用Lipofectamine LTX介导外源DNA转染水牛肾脏成纤维细胞,探讨脂质体用量、质粒用量、质粒大小、转染时间、细胞初始接种密度对转染效率的影响。结果表明,4 μg pmaxGFP质粒DNA与4 μL脂质体转染6 h,其细胞活性达98%,可获得较满意的转染效率。

Abstract: The aim of the present study was to obtain the highest transfection efficiency by liposome induced exogenous DNA to buffalo fetal fibroblasts. In the study, the exogenous DNA was transfected into buffalo fetal fibroblasts using Lipofectamine LTX. The impacts of liposome amount, plasmid amount and size, transfection time course, initial plated density and different promoter used on transfection efficiency were discussed according to the GFP marker gene. It was indicated that 4 μg pmaxGFP plasmid DNA with 4 μL liposome resulted in the highest transfection efficiency and its cell activity was up to 98% after 6 h transfection.

Key words: liposome; fibroblasts; transfection; buffalo
