描述 | SignalSilence® IκBα siRNA I from Cell Signaling Technology (CST) allows the researcher to specifically inhibit IκBα expression using RNA interference, a method whereby gene expression can be selectively silenced through the delivery of double stranded RNA molecules into the cell. All SignalSilence® siRNA products from CST are rigorously tested in-house and have been shown to reduce target protein expression by western analysis. |

背景 | The NF-κB/Rel transcription factors are present in the cytosol in an inactive state complexed with the inhibitory IκB proteins (1-3). Activation occurs via phosphorylation of IκBα at Ser32 and Ser36 followed by proteasome-mediated degradation that results in the release and nuclear translocation of active NF-κB (3-7). IκBα phosphorylation and resulting Rel-dependent transcription are activated by a highly diverse group of extracellular signals including inflammatory cytokines, growth factors, and chemokines. Kinases that phosphorylate IκB at these activating sites have been identified (8). |

Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Unconjugated) #6568 (-) or SignalSilence® IκBα siRNA I (+), using IκBα Antibody #9242 (upper) or α-Tubulin (11H10) Rabbit mAb #2125 (lower). The IκBα Antibody confirms silencing of IκBα expression, while the α-Tubulin (11H10) Rabbit mAb is used as a loading control.Western免疫印迹。用IκBα Antibody #9242 (上图) 或α-Tubulin (11H10) Rabbit mAb #2125 (下图) 研究转染了100 nM SignalSilence® Control siRNA (Unconjugated) #6568 (-) 或 SignalSilence® IκBα siRNA I (+) 的HeLa细胞的细胞提取液。IκBα Antibody 证实了对IκBα蛋白表达的沉默, α-Tubulin (11H10) Rabbit mAb作为上样量的对照。 |
