摘要 目的研究量子点标记人舌癌Tca8113细胞survivin siRNA的方法,为后期以量子点为载体转染siRNA进行基因沉默的研究提供理论依据及技术支持。方法表面带正电荷的水溶性量子点,通过正负电荷的吸引力与表面带负电荷的survivin siRNA结合,在siRNA定量的基础上改变量子点的量,取3种比例进行实验,并设立阳性对照组(siRNA 6μL)、阴性对照组(量子点9μL),通过琼脂糖凝胶电泳观察siRNA条带的亮度分析量子点标记siRNA的最佳比例。结果实验组的siRNA条带亮度均比阳性对照组小,其中siRNA 6μL∶量子点9μL的实验组的siRNA条带亮度最小且与阴性对照组接近,说明该组中量子点与siRNA结合最佳。结论量子点标记人舌癌Tca8113细胞survivin siRNA的最佳比例为1∶2,且该比例在量子点的安全使用范围内。
