Product Details

Effectene Transfection Reagent is a nonliposomal lipid reagent for DNA transfection into a broad range of cell types. Due to its low cytotoxicity, Effectene Transfection Reagent is highly suitable for transfection of primary cells and many sensitive cell lines.

Performance

Higher transfection efficiencies of plasmid DNA are achieved with Effectene Transfection Reagent than with other reagents when used with the recommended procedures (see figure " High transfection efficiencies using Effectene Reagent"). Effectene Transfection Reagent is suitable for transfecting sensitive cell lines with oligonucleotides (see figure " Transfection of oligonucleotides using Effectene Reagent") and is particularly effective for primary cells (see figure " 40% transfection efficiency in primary cells"). Many cell lines and primary cells have been successfully transfected using Effectene Reagent; cell type-specific transfection protocols are available. Cytotoxicity is minimal  because transfection with Effectene Reagent can be performed in the presence of serum and requires low amounts of DNA (see figure " Serum and DNA quantity vs. transfection efficiency"). 

The application of recombinant DNA technology to fields such as drug discovery and development has led to an increased need for high-throughput transfection. Transfection using Effectene Transfection Reagent requires low amounts of DNA and minimal handling. In addition, removal of transfection complexes is not required, making this reagent highly suitable for high-throughput screening. Effectene Transfection Reagent is available in bulk quantities.

Principle

Effectene Transfection Reagent is an innovative non-liposomal lipid formulation that is used in conjunction with a special DNA-condensing enhancer and optimized buffer to achieve high transfection efficiencies. The enhancer first condenses the DNA molecules and Effectene Reagent subsequently coats them with cationic lipids providing a particularly efficient way of transferring DNA into eukaryotic cells. This feature ensures excellent reproducibility of transfection complex formation.

Procedure

The Effectene procedure has two steps. DNA is first mixed with Enhancer and a buffer that provides optimal salt conditions for efficient DNA condensation. This step requires just 2–5 minutes. Effectene Reagent is then added and the mixture is incubated for 5–10 minutes to allow Effectene–DNA complexes to form. The complexes are mixed with growth medium (which can contain serum and antibiotics), and added directly to the cells. The cells are then incubated until harvested and analyzed for gene expression (see flowchart " Effectene transfection procedure").

See figures

Applications

Effectene Transfection Reagent is suitable for transient and stable transfection of a broad range of cell types.

FAQ

What are your recommendations for cotransfecting several plasmids?
The recommended amount of DNA being transfected should be split between the different plasmids. For example, if you normally transfect 5 µg of one plasmid, use 2.5 µg each for two plasmids (other proportions of the two plasmids can be used, as long as 5 µg total is maintained) as a starting point for optimization.

FAQ ID -1030
What is the principle behind Effectene Transfection Reagent?

Effectene Reagent is a unique non-liposomal lipid formulation. Effectene Reagent is used in conjunction with an Enhancer and a DNA-condensation buffer (Buffer EC) to achieve high transfection efficiencies. In the first step of Effectene–DNA complex formation, the DNA is condensed by interaction with the Enhancer in a defined buffer system. Effectene Reagent is then added to the condensed DNA to produce Effectene–DNA complexes. The Effectene–DNA complexes are mixed with medium and directly added to the cells.

Effectene Reagent spontaneously forms micelle structures that show no size or batch variation, as found with preformulated liposome reagents. This unique feature ensures excellent reproducibility of transfection-complex formation. The process of condensing DNA molecules and then coating them with Effectene Reagent is a particularly effective way to transfer DNA into eukaryotic cells.

Broad cell line spectrum

Effectene Transfection Reagent has been used for transfection of a variety of different cell lines and primary cells, and yields significantly better transfection results than many widely used liposome-based transfection reagents. A searchable list of cell lines and primary cells successfully transfected using Effectene Reagent, as well as customer-developed protocols, is available at the Transfection Tools web site.

FAQ ID -184
How can I improve transfection efficiency using Effectene Transfection Reagent?

The following paramenters can be optimized to increase transfection efficiency when using Effectene Transfection Reagent:

Optimize the Effectene Reagent to DNA ratio

If the ratio of Effectene Reagent to DNA is suboptimal, the overall charge of the complexes may be negative, neutral or strongly positive, which can lead to inefficient adsorption to the cell surface. Optimize the Effectene Reagent to DNA ratio according to the section " Transfection Optimization" of the Effectene Transfection Reagent Handbook.

Increase the amount of Effectene-DNA complex

If the transfection efficiency is lower than expected and cytotoxicity acceptably low, increase the overall amount of Effectene-DNA complexes. See the pipetting scheme in the section "Transfection Optimization" of the Effectene Transfection Reagent Handbook for details.

Optimize the incubation time for gene expression

Different cell types achieve maximal expression levels at different times post-transfection. This should be kept in mind when determining length of incubation after transfection. If the time point of maximal expression is not known for a particular cell line, a time course experiment may be necessary.

Consider vector influences

Factors such as the promoter, origin of replication, and plasmid size influence gene expression rate. The optimal quantity of plasmid DNA used for transfection is dependent on the expression rate of the plasmid.

Optimize cell density at the time of Effectene-DNA complex addition

If cell density is too high at the time of transfection-complex addition, cells may not be at the optimal phase of growth. This can lead to insufficient uptake of the complexes into the cells or insufficient expression of the gene of interest. For adherent cells, the optimal confluency at the time of transfection complex addition is normally 40-80%.

Use high-quality DNA Plasmid DNA used for transfection should be of high quality

Impurities present in the DNA preparation can potentially lower transfection efficiency. DNA should be purified using HiSpeed, QIAfilter, or QIAGEN Plasmid Kits or an equivalent method. For endotoxin-sensitive cell lines and primary cells, we recommend using DNA purified with EndoFree Plasmid Kits to ensure the highest transfection efficiencies.
