Label-IT RNAi Delivery Control Cy3 Image Data

Label IT® RNAi Delivery Controls Allow Quick Assessment of Delivery Efficiency For In Vitro Applications. HeLa cells were transfected in serum-containing media with (A) Label IT® Cy®3 RNAi Delivery Control (red) using the TransIT-siQUEST® Transfection Reagent and (B) Label IT® Fluorescein RNAi Delivery Control (green) using the TransIT-TKO® Transfection Reagent. Twenty-four hours post-transfection, the cells were fixed, then counterstained to locate the nuclei (blue) and the actin (green).

Visualization of the Label IT® Cy®3 RNAi Delivery Control in Liver Sections Following Tail Vein Injection. TransIT®-QR Hydrodynamic Delivery Solution was used to deliver 25 µg of Label IT® Cy®3 RNAi Delivery Control (red) to a mouse using hydrodynamic delivery via the tail vein. Forty-five minutes post-injection the liver was harvested. Sections were processed to stain the nuclei (blue) and to stain the actin (green).
