- Add 2 ml of culture medium of E.coli which cultured in overnights into an Eppendorf tube. Then, centrifuge the tube in room temperature (23~25℃), 130000 rpm for one minute.
- Add 250 μl Buffer P1 into the tube. Then, stir it with Vortex until deposition disappears.
- Add 250 μl Buffer P2 and mix the contents by inverting the tube (Don’t use the Vortex)
- Add 350 μl Buffer N3 and mix the contents by inverting the tube (Don’t use the Vortex.
- Centrifuge the tube in room temperature, 13000 rpm for 10 minutes.
- Move the supernatant by a pipette from the tube to the QIAprep Spin Column.
- Centrifuge in room temperature, 13000 rpm for 1 minute and throw away the flow through liquid which collected at the bottom of the column.
- Add 500 μl Buffer PB and centrifuge the tube in room temperature, 13000 rpm for 1 minute. Then, throw away the flow through liquid.
- Add 500 μl Buffer PE and centrifuge the tube in room temperature, 13000 rpm for 1 minute. Then, throw away the flow through liquid.
- Set the upper part of the QIAprep Spin Column into another Eppendorf tube.
- Add 50 μl EB buffer and left it at room temperature for 1 minute.
- Centrifuge in room temperature, 13000 rpm for 1 minute. The flow through liquid is the plasmid DNA solution.

- Incubate them at 37℃ for 1 hour.
- Incubate them at 60℃ for 15 minutes.
- Agarose gel
- TAE Buffer
- Loading Buffer
- DNA solution
- Eppendorf tube
- Ethidium bromide
- Set gel in the electrophoresis tank anf pour the TAE Buffer into the tank.
- Put DNAsolution and Loading Buffer in the ratio of 1:2 into the Eppendorf tube and mix them.
- Load samples into wells.
- Do Electrophoresis at 100V for 40min.
- After electrophoresis, soak the gel into water including ethidium bromide for 20min.
- Observe the bands by ultraviolet radiation.
