Western blot analysis of extracts from HeLa cells, mock transfected or transfected with nonspecific (control) siRNA or SignalSilence® Survivin siRNA I, using Survivin (6E4) Mouse mAb #2802 and p42 MAP Kinase (Erk2) Antibody #9108. The survivin antibody confirms silencing of survivin expression, while the p42 MAPK antibody is used to control for loading and specificity of survivin siRNA.Learn more about how we get our images

CST recommends transfection with 100 nM Survivin siRNA I 48 to 72 hours prior to cell lysis. For transfection procedure, follow protocol provided by the transfection reagent manufacturer. Please feel free to contact CST with any questions on use.
SignalSilence® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.
SignalSilence® Survivin siRNA I from Cell Signaling Technology (CST) allows the researcher to specifically inhibit survivin 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.
Survivin is a 16 kDa anti-apoptotic protein highly expressed during fetal development and cancer cell malignancy (1). Survivin binds and inhibits caspase-3, controlling the checkpoint in the G2/M-phase of the cell cycle by inhibiting apoptosis and promoting cell division (2,3). This regulatory process requires the phosphorylation of survivin at Thr34 by p34 cdc2 kinase (4). Gene targeting using a Thr34 phosphorylation-defective survivin mutant, as well as antisense survivin, have been shown to inhibit tumor growth (5,6).
