Figure 4: Microscopic images of EGFP expressing cells which were not transfected with polyplexes (control; (a)–(c)) versus cells transfected with CS/PLA/siRNA at the weight ratio of 5 : 0.5 : 1, pH 7.4 ((d)–(f)). The images were observed under bright field ((a) and (d)), merge field ((b) and (e)), and fluorescence field ((c) and (f)) microscopy at the magnification of 100x.
