Proportion of APB-positive C7 cells after treatment with siRNAs and 4-hydroxytamoxifen (4OHT).

aCells were transfected with 10 nM siRNA 48 h prior to the addition of 1 µM 4OHT, which was maintained for another 3 days. None, no siRNA-treatment; control, non-silencing control siRNA.将细胞以10 nM（10纳摩尔）的小干扰RNA（small interfering RNA, siRNA）进行转染，于转染48小时后加入1 µM（1微摩尔）的4-羟基他莫昔芬（4-hydroxytamoxifen, 4OHT），并维持该处理条件继续培养3天。分组说明如下："None"组为未进行siRNA处理的样本；"control"组为使用非沉默对照siRNA处理的样本。
