Chemical transfection reagents have been shown to reduce growth and viability of cells after transfection, possibly tlx a result of changes in the strength of the cell membrane.

The complexes were incubated on the cells for 3 h before 1 mL complete medium was added. Complexes were incubated for 10 min. EGFP expression detection by flow cytometry. It has been reported that some cationic liposome transfection reagents could lead to autofluorescence in fluorescent microscopy and flow cytometry analysis, 38 but our results for mock transfection ltz Lipofectamine and Lipofectamine LTX showed no autofluorescence.

Lipofectamine LTX was added, and the complexes were allowed to form by incubation for 25 min.

An electroporation protocol for efficient DNA transfection in PC12 cells.

Viral transduction is particularly efficient for gene transfer and is favored for in vivo use. Methods Mol Biol ; Therefore, measurement of EGFP expression by flow cytometry may underestimate the total number of cells that was gene-modified initially.


Optimal expression of transfected genes in vitro is influenced by many factors, including cell type, passage history, confluence, vector structure, size and purity, promoters, a DNA: J Biol Chem ; Medium was removed from the cells, replaced with complexes, and incubated. Identification of replicative senescence-associated genes in human umbilical vein endothelial cells by an annealing control primer system. Toward development of artificial viruses lltx gene therapy: D Lipofectamine LTX 6.

Mol Ther ; 5: J Cell Sci ; Increasing the time to analysis from 24 h to 48 h resulted in an increased proportion of EGFP-positive cells for some reagents but also caused a reduction in cell viability.

Bioconjug Chem ; Mol Ther ; This article has been cited by other articles in PMC. A number of reasons have been considered to explain these differences.

National Center for Biotechnology InformationU. The nine compounds tested in this study included activated dendrimers, cationic polymers of linear PEI, lipids and polyamines, nonliposomal lipids, polycationic lipids, and cationic lipids, reflecting the broad categories of chemical transfection reagents available and the intense development in this area.


Villemejane J, Mir LM. Curr Drug Deliv ; 1: Differences in EGFP expression were dependent mainly on transfection reagent. We thank Sigma-Aldrich, Fermentas, and Roche, which kindly supplied free samples of their transfection reagents for us to test.

J Pharm Sci ; This project was funded by the Cancer Society of New Zealand. Dachs, unpublished were used as negative and positive controls, respectively. Support Center Support Center. Arch Biochem Biophys ; Importantly, dead cells tend to detach from the growth surface and thus, were not analyzed in this study. Nine commercially available transfection reagents were tested using a range of DNA: Author information Copyright and License information Disclaimer.
