*Purification :The incubated samples were mixed with 400 μL of phosphate‑buffered saline (PBS) and transferred into 50 kDa molecular‑weight‑cut‑off (MWCO) centrifugal ultrafiltration units. Samples were centrifuged at 10,000 × g for 3 min, the retentate was brought back to volume with PBS, and the centrifugal ultrafiltration step was repeated; this wash/centrifugation cycle was performed a total of three times

  • Program folding in PCR thermocycler : The mixed sample was put on a thermal ramp starting with a rapid heat denaturation at 80 °C for 5 min followed by cooling from 80 °C to 60 °C over 20 min, then slow cooling from 60 °C to 24 °C over 14 h.
  • Purification :The incubated samples were mixed with 400 μL of phosphate‑buffered saline (PBS) and transferred into 50 kDa molecular‑weight‑cut‑off (MWCO) centrifugal ultrafiltration units. Samples were centrifuged at 10,000 × g for 3 min, the retentate was brought back to volume with PBS, and the centrifugal ultrafiltration step was repeated; this wash/centrifugation cycle was performed a total of three times

琼脂糖凝胶电泳(1.23)[edit]

  1. 2.4g琼脂糖加入到120 ml(0.5X TBE)中,微波炉加入至完全溶解;用 0.5X TBE 补足,再加入 1.2ml 1M MgCl2 和 12 ul Goldview;倒入模具,插上梳子。
  2. 取Scaffold、Origami(50nM)、Origami(100nM)、Origami(150nM)各 10 ul, 各加入 Loudingbuffer 2 ul,涡旋混匀。
  3. Scaffold、Origami(50nM)、Origami(100nM)、Origami(150nM)依次上样,90V 3h(电泳液:0.5X TBE + 10mM MgCl2)

结论:150 nM 浓度太低
