摘要
目的 :观察人诱导型一氧化氮合酶 (iNOS)基因转染 3T3成纤维细胞的可能性。 方法 :用阳性脂质体将含人iNOS基因的真核表达载体pcDNA3.0 iNOS转染至 3T3成纤维细胞 ,用G4 18筛选 ,通过RT PCR、免疫组化的方法鉴定。 结果 :pcDNA3.0 iNOS基因转染的 3T3细胞有人iNOS基因mRNA和iNOS蛋白的表达。 结论 :iNOS基因能在 3T3成纤维细胞得到稳定转染和表达 ,能为模拟体内一氧化氮 (NO)作用提供有力的工具。
Objective:To observe the feasibility of transfection human nitric oxide synthase in 3T3 cells.Methods:The eukaryotic expression vector pcDNA3.0-iNOS was transfected into 3T3 cells.After screening with G418 and cloning,the cells were verified with RT-PCR and immunofluorescence staining. Results:the expression of iNOS mRNA and iNOS protein in 3T3 cells transfected with pcDNA3.0-iNOS was detected. Conclusion:the 3T3 cells transfected with pcDNA3.0-iNOS can be a useful tool to study the function of nitric oxide in vivo.
