SignalSilence® ILK1 siRNA I: Image 1
Western blot analysis of extracts from HeLa cells, transfected with 50 nM non-targeted siRNA (-) or 100 nM SignalSilence® ILK1 siRNA I (+), using ILK1 Antibody #3862 and Cofilin Antibody #3312. The ILK1 antibody confirms silencing of ILK1 expression and the cofilin antibody controls for protein loading and specificity of ILK1 siRNA.

Product Usage Information

CST recommends transfection with 100 nM ILK1 siRNA I 48 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.

Each vial contains the equivalent of 100 transfections, which corresponds to a final siRNA concentration of 100 nM per transfection in a 24-well plate with a total volume of 300 μl per well.


SignalSilence® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.

Product Description

SignalSilence® ILK1 siRNA I from Cell Signaling Technology (CST) allows the researcher to specifically inhibit ILK1 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.


Integrin-linked kinases (ILKs) couple integrins and growth factors to downstream pathways involved in cell survival, cell cycle control, cell-cell adhesion and cell motility (1). ILK functions as a scaffold bridging the extracellular matrix (ECM) and growth factor receptors to the actin cytoskeleton through interactions with integrin, PINCH (which links ILK to the RTKs via Nck2), CH-ILKBP and affixin (1). ILK phosphorylates Akt at Ser473, GSK-3 on Ser9, myosin light chain 2 (MLC2) on Ser18/Thr19, as well as affixin (2-5). These phosphorylation events are key regulatory steps in modulating the activities of the targets. ILK activity is stimulated by PI3 kinase and negatively regulated by the tumor suppressor PTEN and a PP2C protein phosphatase, ILKAP (1,3,6). It has been suggested that the conserved Ser343 residue in the activation loop plays a key role in the activation of ILK1 (2).
Small Interfering RNA (siRNA) has been used to specifically silence ILK expression in HEK-293 cells (7).
