Arch Biochem Biophys ; This project was funded by the Cancer Society of New Zealand. Currie1 Bridget A. Open in a separate window. Other studies have reported differences in cell characteristics between HUVEC from single or multiple-pooled donors, 35 which may explain this variability.

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 lipofectamjne of transfected HUVEC for use in subsequent assays.

An electroporation protocol for efficient DNA transfection in PC12 cells.

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. The complexes were added to cells in 2 mL complete medium and incubated. BoxChristchurchNew Zealand Phone: This article has been cited by other articles in PMC. The proportion of EGFP-positive cells is presented on the graphs. Abstract Primary cells, such as HUVEC, are notoriously difficult to transfect and are susceptible to the toxic effects of transfection reagents.


An equal volume of PLUS reagent was added. Hum Gene Ther ; For three of the reagents Effectene, Escort IV, and ExGenthe final amount of DNA played a role in transfection efficiency, with more DNA in the mixture associated with increased transfection efficiency results not shown.

Cytokines Mol Ther ; 2: A transfection reagent with a high transfection efficiency and low cytotoxicity was sought to retain sufficient viability of transfected HUVEC for subsequent assays. High-efficiency transient transfection of endothelial cells for functional analysis.

DNA was added to the mixture and the complexes incubated for 15 min.

On the other hand, luciferase activity, detected via conversion of a substrate, resulting in amplified signal, determines the behavior of the entire population, thereby losing information about single cells.

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.
