Gel retardation assay of siRNA/ELPs complexes. a Condensations of siRNA (10 µM) and ELPs (50–300 µM) were monitored at molar ratios from 1:5 to 1:30 (siRNA: ELPs). b Stability of encapsulated siRNA was determined by treating siRNA/ELP complex with or without RNase A for 6 h. c–f Changes in thermal behaviors of resulting siRNA/ELP complexes were compared with naïve ELPs by measuring turbidity profiles at 350 nm while increasing temperature at 1 °C/min
