Description_x000D_ General description_x000D_ The MISSION® siRNA Transfection Reagent is for the transfection of siRNA to achieve ≥90% silencing efficiency for transient knockdown of eukaryotic gene expression._x000D_ Effective gene silencing and reduced off target effects are achieved using a low siRNA concentration (1nM). The siRNA Transfection Reagent is provided as a sterile solution, and is compatible with serum and antibiotics._x000D_ Other Notes_x000D_ Gene silencing assay: An A549 cell line stably expressing firefly luciferase was transfected in 24-well plates with 8.4 ng of 21-mer Luciferase siRNA using 2 μL of the MISSION® siRNA Transfection Reagent. Experiments were performed in triplicate in presence of serum. Cell lysates were assessed for luciferase expression 48 hours post-transfection._x000D_ Legal Information_x000D_ MISSION is a registered trademark of Sigma-Aldrich Co. LLC
