Anticorps, Protéines recombinantes, coffret ELISA, RNAi, clones ADNc, Antibody Array.. Polyethylenimine (PEI) has gained progressive relevance as transfection carrier for insect cell/TGE approaches, since transfection efficiencies are high, it is cheaper than the majority of commercial reagents and the overall cost of the bioprocess is reduced . This is of great importance for the production at larger scales in order to meet the increasing demand of therapeutic and diagnostic. DNA can be introduced into a host cell by transfection with polyethylenimine (PEI), a stable cationic polymer (Boussif et al., 1995). PEI condenses DNA into positively charged particles that bind to anionic cell surfaces Polyethylenimin (Abk.: PEI) ist formal das Polymerisierungsprodukt seines Monomers Ethylenimin, besser bezeichnet als Aziridin.. Ethylenimin (Aziridin) ist entgegen der Bezeichnung kein Imin, da in ihm der Stickstoff keine Doppelbindung zu einem Kohlenstoffatom aufweist, sondern zwei Einfachbindungen zu zwei verschiedenen C-Atomen und daher ein sekundäres Amin

Polyethylenimine (PEI) transfection of mammalian cells in culture. DNA Plasmid name: Length (in basepairs) of DNA to be transfected Polyethylenimine (PEI) Poly(ethylenimine) was the second polymeric transfection agent discovered, after poly-l-lysine. PEI condenses DNA into positively charged particles, which bind to anionic cell surface residues and are brought into the cell via endocytosis. Once inside the cell, protonation of the amines results in an influx of counter-ions and a lowering of the osmotic potential.

In search for a cheap and effective transfection reagent we used the positively charged polyplex-forming compound polyethylenimine (PEI). This compound is commercially available from different companies either as a non-modified chemical reagent or with additives as a more cost intensive transfection reagent. Here we used the non-modified PEI reagent to optimize transfection protocols for. This process may involve choosing a new transfection reagent. For example, one reagent may work well with HEK-293 cells, but another reagent may be a better choice when using HepG2 cells. Promega provides the FuGENE® HD Protocol Database to help identify a protocol for your cell line when using the FuGENE® HD Transfection Reagent. A drop-down menu allows you to search the database by cell.

We have found a way to make possible large-scale plasmid transfection using PEI to produce high titer viral vectors in fixed bed or adherent cell culture bioreactors by using PEI as a transfection agent, while avoiding formation of the PEI-plasmid precipitate which in prior art approaches clogged adherent bioreactor substrates.

Figure 10 illustrates the transfection rate for DNA/PEI max/MNP (γ-Fe 2 O 3 of 2.25 μg) complexes in the presence of chlorpromazine as a CDE inhibitor and genistein as a CIE inhibitor. The transfection rate was decreased by both endocytic inhibitors, showing that the complexes were internalized by CDE and CIE. This result agrees with those of previous studies (Huth et al. 2004). DNA/PEI max. If there is a need to decrease the volume of the transfection mix, increased plasmid DNA concentration may not accomplish optimal DNA-PEI precipitation, and may lead even to DNA aggregation, rendering the DNA in a physical aggregate physically too large to properly transfect a host cell. To prevent aggregation, we surprisingly have found that a shorter transfection mix incubation time before. The same expression levels were obtained with both PEI variants (data not shown), and since PEI max 40 kDa is easier to handle this variant was chosen for the experiments described in this study. The expression efficiency and cost per produced amount of antibody was compared with the PEI Max 40 kDa transfection protocol and the ExpiFectamine transfection protocol that ThermoFisher provides.
