不同转染方法对逆转录病毒转染效率影响的研究 |
|
【摘要】 目的 探讨不同加样方法对逆转录病毒转染软骨细胞效率的影响。方法 将构建并包装好的逆转录病毒重组基因PLNCX2IL1RaGFP分别采用以下加样转染方法进行转染并作对照研究,a)第1组:先加病毒上清,6 h后补充培养液;b)第2组:先加病毒上清,隔夜补充培养液;c)第3组:先加病毒上清,6 h后更换成培养液,隔夜培养后弃液,重复先加病毒上清,6 h后更换成培养液;d)第4组:先加病毒上清,6 h后补充培养液,隔夜培养后弃液,重复先加病毒上清,6 h后补充培养液;e)第5组:经典转染法,同时加病毒上清液和培养液。转染2 d后免疫荧光显微镜下观察荧光显色,4周稳定转染后分别检测各组细胞培养液中NO含量,并用ELISA法检测上清液中hIL1Ra的表达情况。结果 酶切鉴定重组基因正确;免疫荧光显微镜观察可见绿色荧光显色;1~5组NO含量以第4组为最高,第5组为最低;ELISA检测1~5组培养液中hIL1Ra的含量以第4组为最高,第5组为最低。结论 四种不同加样转染方法的转染效率均高于经典法,其中以第4组为最好。
