- Origami folding
折叠三种浓度的Origami（50nM,100nM,150nM）
| Samples | Volume |
|---|---|
| Scaffolld (1uM) | 5 ul |
| Staples (10uM) | 2.5 ul X 9 |
| PBS (10X) | 10 ul |
| Water | 62.5 ul |
| Samples | Volume |
|---|---|
| Scaffolld (1uM) | 10 ul |
| Staples (10uM) | 5 ul X 9 |
| PBS (10X) | 10 ul |
| Water | 35 ul |
| Samples | Volume |
|---|---|
| Scaffolld (1uM) | 15 ul |
| Staples (10uM) | 7.5 ul X 9 |
| PBS (10X) | 10 ul |
| Water | 7.5 ul |
- 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)
- 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。
- 取Scaffold、Origami（50nM）、Origami（100nM）、Origami（150nM）各 10 ul， 各加入 Loudingbuffer 2 ul，涡旋混匀。
- 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
