Fig. 2.
(A) Particle size and zeta potential of PAM-ABP/siRNA polyplexes at weight ratios ranging from 0.2 to 10 based on siRNA (4 μg). (B) Particle size and zeta potential of PAM-ABP/siRNA polyplex (weight ratio 1:5, siRNA(4 μg)) and PEI/siRNA polyplex (weight ratio 1:1, siRNA (4 μg)) with 5 mM DTT or without DTT. The results are presented as mean ± SD (n=3).
