Figure 4. Transfection efficiencies of lipid-coated magnetic nanoparticles in adult dog retinal endothelial cells

Three different concentrations of transcriptionally active PCR products (TAP; white bars) were used (100, 200, and 400 ng per well of 24 well plates) either alone or tethered to lipid-coated nanoparticles (MNP; red bars). Approximately 1000 cells were analyzed for each data point. The bars represent the mean of 3 wells; the error bars represent the standard error of the mean. These data show that TAP tethered magnetic nanoparticles are better at transfecting cells than free TAP in the 200 and 400 ng groups.
