Escort™ IV Transfection Reagent

Description

• General description: Escort™ IV is a unique formulation of a proprietary polycationic lipid and a neutral non-transfecting lipid. This liposome-forming compound is used for transfection of nucleic acids into a wide variety of eukaryotic cell types.
• Application: Suitable for transient and stable transfection of nucleic acids into cultured eukaryotic cells. Use approximately 4-16 μL Escort™ IV and 2 μg DNA per 6 cm cell culture plate. Protocol optimization provides very efficient transfection. For a list of cells that have been successfully transfected using Escort™ IV, see the Transfection Reagent Selection Guide.
• Features and Benefits: Suitable for stable and transient transfection Optimized for a wide variety of cell linesLow toxicityCompatible with both serum and serum-free transfection protocols Ideal for Sf9, Sf21 and S2 insect cells
• Components: Escort™ IV formulation:1 mg/mL total lipid in waterNote the identity of the lipids used in Escort™ IV is confidential.
• Caution: Do not freeze.
• Principle: A stable complex is formed when Escort™ IV is mixed with DNA in the absence of serum. The complexes are stable and can be directly added to the cell culture medium, where they fuse with the cell membrane, releasing the DNA into the cytoplasm. Note: complex formation is inhibited by serum, but once stable complexes have formed, the presence of serum is without consequence.
