GeneSilencer® siRNA Transfection Reagent is a novel cationic lipid formulation specifically designed for efficient delivery of siRNAs (small interfering RNAs) into a wide variety of cell types. siRNAs are short, gene-specific double-stranded RNAs that can cause gene silencing in mammalian cells by catalytically cleaving greater than 95% of the target mRNA (1,2,3).
