Stability of micelle. (a) Diffusion coefficient of micelles after incubation with sodium dextran sulfate at different S/P (sulfate in dextran sulfate/phosphate in mRNA) ratios for 1 h. The upper dashed line represents the diffusion coefficient of naked mRNA. Data were expressed as the mean ± s.d. (n = 10). (b) Remaining mRNA after incubating micelles with serum at 37 °C for 15 min. The mRNA amount was measured by qRT-PCR. Data were expressed as the mean ± s.d. (n = 3). p-value was calculated by the two-tailed Student’s t-test.
