Effects of nanoparticles on viability of HEK293FT cells.

<p>Cells in 24-well plate were subjected to MTT assay after incubation with different amounts of PLGA+DNA (DNA adsorbed on PLGA nanoparticles, 6:1, w/w), bPEI-DNA (3:1, w/w), or PLGA/bPEI-DNA (6:3:1, w/w/w) corresponding to the indicated polymer concentrations (PLGA+bPEI) (left panel). On the right panel, cell viability was tested after incubation with PLGA/bPEI-DNA (6:3:1, w/w/w, 24 well tested) for varying amount of time. n=3.
