Transgene expression for surface treatment, and adsorption efficiency and expression levels for multiple deposition methods. (A) Transgene expression for PLG surfaces with and without pre-hydrolyzing treatment. DNA complexes were mixed with ECM (25 μg) and subsequently dried on PLG disks. Significant differences based on a t-test between surfaces with and without pre-hydrolyzing treatment are denoted by an asterisk (p<0.05). (B) Immobilization efficiency of DNA complexes onto ECM (25 μg) coated PLG disks using i) incubation, ii) 2-step drying, and iii) 1-step drying. (C) Transgene expression in vitro using the three deposition methods. Significant differences based on a Tukey multiple comparisons analysis are denoted by different letters (p<0.05).
