Combining ability and protecting effects of shBcl-2-loaded NPs by agarose gel electrophoresis. Gel retardation assay for determining loading ability of shBcl-2 in NPs (A), DNaseI protection of shBcl-2-loaded NPs (B), and serum protection of shBcl-2-loaded NPs (C). (Lane 1: naked shBcl-2; lanes 2 to 4, shBcl-2-loaded NPs prepared at mass ratios of 50,100, and 200, respectively).
