Summary
jetPEI®-Hepatocyte is a DNA transfection reagent designed to transfect Hepatocyte-like cells. jetPEI®-Hepatocyte is recommended to transfect primary hepatocytes and cell lines such as human hepatocarcinoma Hep G2 and murine hepatocytes BNL-CL.2.
jetPEI®-Hepatocyte is a Galactose-bearing linear polyethylenimine designed to enhance the transfection of cells expressing Galactose-specific membrane lectins, such as hepatocytes that express the asialoglycoprotein receptor (ASGP-R or Gal/GalNAc receptor). Cell targeting is the result of binding of the Galactose residues to the specific cell-surface receptors, leading to internalization of the DNA complexes.

Description
jetPEI®-Hepatocyte leads to improved transfection efficiency of hepatocarcinoma Hep G2 cells
Compared to our standard jetPEI® transfection reagent, jetPEI®-Hepatocyte provides significantly higher transfection efficiencies in human hepatocarcinoma Hep G2 cells as well as in difficult to transfect primary human hepatocytes (Fig. 1).
Fig. 1: Comparative transfection efficiency of jetPEI®-Hepatocyte versus jetPEI®. Hep G2 (50,000 cells in 24-w) and primary human hepatocytes (100,000 cells in 24-w) were transfected using 3.2 µl of both reagents with 1 µg of pCMVEGFPLuc, in 1 ml of complete medium containing 10% of serum. The luciferase activity was determined 48h post-transfection. Transfection efficiency was expressed as relative efficiency obtained with jetPEI® compared to jetPEI®-Hepatocyte.
Good transfection efficiency and excellent viability in primary hepatocytes
Primary human hepatocytes show good transfection efficiency (around 50%) 24 h and 48 h after transfection using jetPEI®-Hepatocyte and luciferase plasmid pCMVEGFPLuc. In addition, cells look very healthy (Fig. 2).
Fig. 2: Primary human hepatocytes expressing GFP 24 h and 48 h after transfection using jetPEI®-Hepatocyte. Primary human hepatocytes (100,000 cells in 24-w) were transfected with 1 µg of pCMVEGFPLuc at N/P ratio of 8, in 1 ml of complete medium containing 10% of serum. Cells were visualized by fluorescence microscopy.
Easy transfection of hepatocyte-derived cell lines
The most popular hepatocyte-derived cell lines BNL-CL.2 and Hep G2 were successfully transfected using jetPEI®-Hepatocyte and commonly show approximately 50 % and 30% transfection efficiency, respectively (Fig. 3 and 4).
Fig. 3: BNL-CL.2 cells expressing ß-galactosidase after transfection using jetPEI®-Hepatocyte. NL-CL.2 cells (50,000 cells in 24-w) were transfected using 3.2 µl of reagent with 1 µg of pCMVEGFPLuc, in 1 ml of complete medium containing 10% of serum. -galactosidase gene expression was visualized by X-gal staining after 24h. |
Fig. 4: Hep G2 cells expressing GFP 72 h after transfection using jetPEI®-Hepatocyte. Hep G2 cells (50,000 cells in 24-w) were transfected using 3.2 µl of reagent with 1 µg of pCMVEGFPLuc, in 1 ml of complete medium containing 10% of serum. Cells expressing GFP protein were visualized by fluorescence. |
Easy to use protocol
The jetPEI®-Hepatocyte 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®-Hepatocyte is compatible with serum and antibiotics, thus eliminating the need for media changes. Protein expression is determined 24 h to 72 h post-transfection.
Applications
jetPEI®-Hepatocyte is perfectly suited for plasmid delivery (DNA, shRNA or miRNA) to primary hepatocytes as well as hepatocarcinoma cells, such as Hep G2 and BNL-CL.2.
Quality
Every batch of jetPEI®-Hepatocyte 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.
