Kreppel F, Kochanek S. All protocols are per-well of a six-well plate. BoxChristchurchNew Zealand Phone: Biotechnol Prog ; Written, informed consent was obtained from each woman who donated an umbilical cord approved by Canterbury Ethics Committee R. However, it was observed in this study that transfection efficiencies appear to vary with some batches of HUVEC, and cells extracted from some cords are able to be transfected more efficiently than those from others.
Br J Haematol ; Transfer and expression of foreign genes in mammalian cells.
Inhibition of hydrophobic protein-mediated Candida albicans attachment to endothelial cells during physiologic shear flow. Cancer Gene Ther ; 8: Each point represents a different ratio of reagent: Overcoming the nuclear barrier: Where a ratio was tested more than once, the mean transfection efficiency is plotted.
High-efficiency transient transfection of endothelial cells for functional analysis. Arch Biochem Biophys ; Other studies have reported differences in cell characteristics between HUVEC from single or multiple-pooled donors, 35 which may explain this variability.
siRNA transfection in endothelial cells – siRNA, microRNA and RNAi
Exp Gerontol ; Lipofsctamine from Journal of Biomolecular Techniques: Complexes were added to the cells containing 2 mL complete medium and incubated. Differences in EGFP expression were dependent mainly on transfection reagent.
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. Cytokines Mol Ther ; 2: Lipofectamine LTX was added, and the complexes were allowed to form by incubation for 25 min.
Modification of adenovirus gene transfer vectors with synthetic polymers: J Pharm Sci ; Endothelial cell COX-2 expression and activity in hypoxia. EGFP gene expression allows easy determination of the proportion of cells that is gene-modified on a single-cell basis, detecting the number of cells expressing EGFP and their level of EGFP expression via flow cytometry.
Nonviral approaches for targeted delivery of plasmid DNA and oligonucleotide.

Exp Cell Res ; Mol Ther ; 5: Methods Mol Biol ; Therefore, measurement of Protockl expression by flow cytometry may underestimate the total number of cells that was gene-modified initially. Identification of replicative senescence-associated genes in human umbilical vein endothelial cells by an annealing control primer system. Dual targeting of gene delivery by genetic modification of adenovirus serotype 5 fibers and cell-selective transcriptional control.
Chemical transfection reagents have been shown to reduce growth and viability of cells after lipofecamine, possibly as a result protkcol changes in the strength of the cell membrane.
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 protocop a reduction in cell viability. J Cell Sci ; Primary cells are considered more difficult to transfect than immortalized cell lines, as they are more susceptible to toxic agents and may degrade exogenous nucleic acids in the cytoplasm.
Improving safety of gene therapy. 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. The gated region for cell debris or necrosis is indicated, as well as the percentage of dead cells according to this method.
