Figure 7From: A novel Poly(ε-caprolactone)-Pluronic-Poly(ε-caprolactone) grafted Polyethyleneimine(PCFC-g-PEI), Part 1, synthesis, cytotoxicity, and in vitro transfection studyThe flow cytometry graphs of the transfection efficiency in two cell lines. (A) 293 T and (B) A549. PCFC-g-PEI and PEI (25 KD) at optimized N/P ratios combine with DNA. A1 and B1 are the controls both used naked DNA, and A2 and B2 are the flow cytometry data that demonstrated the transfection efficiency.Back to article page
