General description

X-tremeGENE 9 DNA Transfection Reagent is a proprietary blend of lipids and other components supplied in 80% ethanol, filtered through 0.2 μm pore size membrane, and packaged in glass vials.


X-tremeGENE 9 DNA Transfection Reagent is a non-liposomal multi-component reagent for experiments involving cellular analysis. Due to its extremely low cytotoxicity, minimal need for optimization, and the ability to provide high transfection efficiency in a wide range of commonly used cell lines even in the presence of serum, it is well suited for applications in all fields of cellular analysis.

X-tremeGENE 9 DNA Transfection Reagent is well suited for cellular analysis applications such as:
  • Expression of recombinant proteins for functional analysis.
  • Physiological studies of metabolic pathways.
  • Analysis of regulatory sequences using reporter gene assays.
  • Gene expression assays.
  • Cancer research studies.
  • Target evaluation.

Features and Benefits

  • Generate physiologically relevant results using a reagent with extremely low cytotoxicity for maximum post-transfection cell viability.
  • Save time and eliminate multiple handling steps; simply dilute X-tremeGENE 9 DNA Transfection Reagent, incubate with plasmid DNA, and pipet the mixture directly onto your cells (with or without serum).
  • Avoid time-consuming optimization procedures in commonly used cell lines.


Each lot of X-tremeGENE 9 DNA Transfection Reagent is carefully tested following established quality procedures to ensure that the product is consistently performing according to specifications. During quality testing, cells are transfected with a reporter gene vector DNA using X-tremeGENE 9 DNA Transfection Reagent (ratio 3:1 μl/μg DNA). Reporter gene activity is monitored via chemiluminescent detection. Using a standard curve, the total amount of recombinant protein is determined per well in order to meet specification.

Physical form

Supplied in 80% ethanol and sterile-filtered through 0.2 μm pore size membrane.Number of Tests: Using the standard procedure, 1 ml of X-tremeGENE 9 DNA Transfection Reagent can be used to perform up to 6,600 transfections in 96-well plates using 3:1 ratio and up to 10,000 transfections using 2:1 ratio.

Other Notes

For life science research only. Not for use in diagnostic procedures.

Reverse Transfection of Plasmid DNA

Automation is used for many applications to reduce variation caused by manual handling and to obtain reproducible results in high-throughput assays. High-throughput applications, such as knockdown studies or target screenings, often include cell transfection.

A Versatile new Lipofection Reagent for co-transfection of DNA and RNA: X-tremeGENE™ siRNA Transfection Reagent

Small inhibitory RNAs (siRNAs) have become the focus of interest in many laboratories. For the first time, these molecules offer an easy way to knock down the expression of selected genes in mammalian cells without having to resort to classical gene knockout techniques.

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.
