原理

Effectene Transfection Reagent是一种全新的非脂质体的脂类转染剂，将DNA 与浓缩增强子和优化的缓冲液混合使用以达到高效转染。浓缩增强子先聚合DNA分子，Effectene Transfection Reagent随后用阳离子脂质包围聚合的DNA分子。采用一种特殊有效的方法将DNA转入真核细胞。这种特性保证了复杂复合物转染的可重现性。

程序

Effectene流程分为两步。将DNA与浓缩增强子混合后，加入Effectene Transfection Reagent形成复合物，这一步只需2–5分钟。然后加入Effectene Transfection Reagent，与混合物一起反应5–10分钟以形成Effectene–DNA复合物。复合物与培养基混合（可以含有血清和抗体），直接加入到细胞中。培养细胞至成熟，分析基因表达（参见" Effectene transfection procedure"）。

High transfection efficiencies using Effectene Reagent.

Transfection efficiencies using Effectene Reagent and two commonly used lipid-based reagents were compared. Murine teratocarcinoma F9 cells (5 x 10⁵) were transfected in 6-well plates with a luciferase-reporter plasmid using optimized conditions based on the manufacturer's instructions for each reagent. Transfection efficiencies were determined by measuring luciferase activity 48 hours post-transfection, and are given as relative light units (RLU). (Data kindly provided by I. Clavereau, D. Petitprez, and I. Van Seuningen, Unité INSERM 377, Place de Verdun, Lille Cedex, France.)

FAQ

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

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

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.
