Overview Image Lipid Reagent Selection Guide Image Transfection Protocol Library Lipid transfection reagents provide optimal transfection efficiencies for nucleic acid delivery into mammalian cells. General use and RNAi-optimized transfection reagents are available. Category Products Image TransFectin™ Lipid Reagent TransFectin reagent is a cationic lipid reagent that delivers the highest efficiencies and expression levels over a broad range of cell lines, including some difficult-to-transfect and primary cells. Image siLentFect™ Lipid Reagent for RNAi siLentFect lipid reagent is a mixture of a proprietary cationic compound and a co-lipid. The blend has been optimized for the delivery of siRNAs into cultured mammalian cells in the presence of serum.
