Fig. 2. Characterization of DNA nanotubes with the overhang structure (NTR). (A) PAGE gel characterization of a DNA nanotube with a miR-155 capturing unit (NTR155). (B) Native PAGE analysis of a DNA nanotube with a miR-21 capturing unit (NTR21). (C) AFM imaging of NTR155. The image size is 500 nm × 500 nm (scale bar: 50 nm). (D) DLS measurement of NTR155. The DNA nanotube concentration for DLS measurements is 100 nM.
