These reagents show promise, as they are produced easily in large quantities, are used rapidly in high-throughput assays, are noninfectious, and can transfer DNA of various sizes.

Fluorescence produced by transfection reagents can be confused with green fluorescent proteins in protockl cells. Methods Mol Biol ; Non-viral gene delivery with cationic liposome-DNA complexes.

Mixtures were incubated for 5 min and then combined together for a further 20 min. Please review our privacy policy. World J Gastroenterol ; Kreppel F, Kochanek S. Antibiotics and antifungal agents were not used during transfection procedures.

This study analyzed nine currently available, commercial transfection reagents and showed that cationic lipid reagents were the most efficient in gene-modifying HUVEC. Our study demonstrated that a small selection of commercially available chemical transfection reagents was able to transfer exogenous genes efficiently to primary human cells.


Differences in EGFP expression were dependent mainly on transfection reagent. Journal List J Biomol Tech v. This led to an underestimation of the total amount of cell death caused by transfection but a more accurate representation of the number of live cells and proportion of EGFP-expressing cells left to plate out for subsequent assays. Transfection efficiency of cationic lipids with different hydrophobic domains in gene delivery.

Other studies have reported differences in cell characteristics between HUVEC from single or lioofectamine donors, 35 which may explain this variability.

An equal volume of PLUS reagent was added.

Cardiovasc Drugs Ther ; 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 lipofecyamine development in this area.

Nine commercially available transfection reagents were tested using a range of DNA: Mock transfection data showed no difference in cell death at 24 h versus 48 h, i. Prtocol the nuclear barrier: Flow cytometry black, AAD-positive cells indicated that cells analyzed after 48 h tended to have more dead cells compared with cells analyzed after 24 h, e.

Cationic liposomes induce macrophage apoptosis through mitochondrial pathway. Cell viability after transfection. 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: There are no financial support or associations that would liporectamine a conflict of interest.

Welsh S, Kay SA. Lipofectamine LTX was identified as the optimal transfection reagent as a result of its higher transfection efficiency at shorter periods of time following transfection when cytotoxicity was limited, allowing sufficient yield of transfected HUVEC for use in subsequent assays.

Infect Immun ; Biol Pharm Bull ; Dachs, unpublished were used as negative and positive controls, respectively.

Robinson1 and Gabi U. L—L [ PubMed ]. 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 using Lipofectamine and Lipofectamine LTX showed no autofluorescence. Transfection complexes were formed at room temperature in serum-free medium prior to drop-wise addition to HUVEC, followed by incubation for various periods and replacement with complete medium for 24 or 48 h.

Complexes were added to the cells containing 2 mL complete medium and incubated. Differential liipofectamine of human endothelial cells to internalize and express exogenous DNA. Inhibition of hydrophobic protein-mediated Candida albicans attachment to endothelial cells during physiologic shear flow.
