jetPEI®-HUVEC is a powerful transfection reagent optimized for the transfection of primary human endothelial cells such as HUVEC (Human umbilical vein endothelial cells). Transfection efficiencies up to 50% have been reached with this reagent.

jetPEI®-HUVEC is also recommended for the transfection of vascular endothelial cells of various origins and appears to be well-suited for such fragile primary cells.

jetPEI®-HUVEC leads to improved transfection efficiency of endothelial cells

 Compared to jetPEI®, our standard and versatile transfection reagent, jetPEI®-HUVEC provides significantly higher transfection efficiencies in HUVEC cells (Fig. 1).

jetPEI-HUVEC - Comparison jetPEI
Fig. 1: Transfection efficiency and toxicity of jetPEI® and jetPEI®-HUVEC in HUVEC. Cells were incubated for 4 h with transfection complexes in 2 % serum medium. Luciferase activity was measured 24 h after transfection.

Indeed, jetPEI®-HUVEC induces less cellular toxicity than jetPEI®. Using the optimal conditions for jetPEI®-HUVEC, transfection efficiencies of 50% have been reached as observed with a fluorescent protein reporter gene (Fig. 2).

Fig. 2: FACS analysis of HUVEC cells transfected with a plasmid encoding the EGFP fluorescent protein using jetPEI®-HUVEC. Transfection was performed in 24-well plate with 2 µg of plasmid and 4 µl of jetPEI®-HUVEC (N/P = 5) and in 2 % serum. Complexes were incubated for 4 h with the cells. FACS analysis to quantify EGFP expression was performed 24 h after transfection.

Optimization of the experimental conditions for high transfection efficiency

The effect of serum concentration and incubation time on transfection efficiency was analyzed (Fig. 3).

jetPEI-HUVEC - Incubation with serum
Fig. 3: Effect of low (2 %) versus high (30 %) serum concentrations on transfection efficiency of jetPEI®-HUVEC. HUVEC cells were transfected for 2, 4 or 24 h with 2 µg of pCMVLuc plasmid DNA and 4 µl of jetPEI®-HUVEC in 24-well plates. Luciferase activity was measured 24 h after transfection.

Transfection experiments performed in low (2 %) or high (30 %) concentrations of serum have shown that jetPEI®-HUVEC is most efficient when the cells are grown in low serum concentrations. Gene expression reaches a maximum for HUVEC after 4 h incubation with DNA/jetPEI®-HUVEC complexes.

jetPEI®-HUVEC compares particularly favorably to other non-viral transfection reagents whether cationic lipids or polyamine (Fig. 4).

Easy to use protocol

The jetPEI®-HUVEC protocol is as simple as the jetPEI® one: Mix the DNA with the reagent to form complexes and simply add the mixture to the cells. jetPEI®-HUVEC is compatible with serum and antibiotics, thus eliminating the need for media change. Protein expression is determined 24 h to 72 h post-transfection.

jetPEI®-HUVEC is perfectly suited for plasmid delivery (DNA, shRNA or miRNA plasmids) to fragile cells, such as primary endothelial cells.

Every batch of jetPEI®-HUVEC is tested in a transfection assay. Typically, transfection of a firefly luciferase gene under the control of the CMV promoter gives 109 RLU (relative light unit)/mg of protein. The value for each batch is indicated on the Certificate of Analysis.
