上机检测前,须用待测细胞制备质控样本来设定流式细胞仪的荧光补偿和设置十字门的范围: (I) 未转染GFP等标记的细胞 ① 空白管:阴性对照组细胞,没有染色的细胞。不加Annexin V/APC,PI。用于调节电压。 ② 单染管:有明显凋亡的细胞,只加Annexin V/APC染色。用于调节补偿。 ③ 单染管:有明显凋亡的细胞,只加PI染色。用于调节补偿 ④ 检测管:待测的处理细胞,加Annexin V/APC,PI。用空白管和单阳管调节好电压补偿后,获得所需要的流式数据。
(II) 转染GFP细胞 ① 未转染空白管:未转染细胞,阴性对照组细胞,没有染色的细胞。不加Annexin V/APC,PI。用于调节电压。 ② 转染GFP空白管:转染GFP的对照组细胞,没有染色的细胞。不加Annexin V/APC,PI。用于调补偿 ③ 未转染单染管:未转染且有明显凋亡的细胞,只加Annexin V/APC染色。用于调节补偿。 ④ 未转染单染管:未转染且有明显凋亡的细胞,只加PI染色。用于调节补偿 ⑤ 检测管:待测的处理细胞,加Annexin V/APC,PI。用空白管和单阳管调节好电压补偿后,获得所需要的流式数据。
