Application of PEI-Modified Magnetic Nanoparticles as Gene Transfer Vector for the Genetic Modification of Animals

Figure 6

The efficiency curve of GFP expression with different amounts of nanoparticle/DNA complexes. The efficiency of GFP expression was influenced by the amount of the nanoparticle/DNA complexes. Efficiency increased with raised amount of complexes in low range, decreased with continuously increasing the amounts of complexes, and then changed not obviously when the complex amount surpassed 4 μg.
