Silencer® siRNA Labeling Kits
Figure 1 shows a silencing experiment performed with a Cy3 labeled GAPDH siRNA and a corresponding Cy3 labeled scrambled siRNA sequence prepared with the Silencer Cy3 siRNA Labeling Kit. The labeled siRNAs were transfected separately into HeLa S3 cells and then imaged by fluorescence microscopy. An anti-GAPDH antibody was used to monitor silencing of GAPDH expression. The siRNA to GAPDH has a strong silencing effect denoted by the lack of GAPDH protein expression (green) in Panel A compared to Panel B where the scrambled siRNA sequence was used. Each Silencer siRNA Labeling Kit comes complete with labeling reagents for 65 µg of siRNA, a GAPDH control for labeling, and a detailed Instruction Manual.
Figure 1. siRNA Silencing of GAPDH Gene Expression. siRNA to human GAPDH and a scrambled control were fluorescently labeled with Cy3 using Ambion's Silencer® siRNA Labeling Kit, transfected into HeLa S3 cells, and analyzed by fluorescence microscopy with an anti-GAPDH antibody. Red: Cy3 labeled siRNA; Blue: DAPI stained nuclei; Green: fluorescein labeled antibody to GAPDH. A. GAPDH is undectable in cells transfected with GAPDH siRNA. B. GAPDH is easily detected in cells transfected with scrambled control GAPDH siRNA.
