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 lines
  • Low toxicity
  • Compatible 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 water

Note 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.

Introduction to Cell Transfection

Transfection is the introduction of DNA, RNA, or proteins into eukaryotic cells and is used in research to study and modulate gene expression. Thus, transfection techniques and protocols serve as an analytical tool that facilitates the characterization of genetic functions, protein synthesis, cell growth and development.

How Transfection Works

This brief webinar provides an overview of what transfection is and the methods that are used to introduce DNA or RNA into eukaryotic cells.
