Protocol



Our experiment was done follow description.


■Plasmid DNA Purification; (QIAGEN)

All centrifuge is done at 13,000rpm, room temperature.

1. Add 1mL overnight cultures of E. coli in LB medium to a eppendorf tube. Centrifuge 1 min and create pellet.
2. Add 250µL Buffer P1 and vortex until pellet perfectly dissolved.
3. Add 250µL Buffer P2 and mix softly by inverting the tube 4-6 times. (Don't vortex.)
4. Add 350µL Buffer N3 and immediately mix softly by inverting the tube 4-6 times. (Don't vortex.)
5. Centrifuge 10 min. Add supernatant to QIAprep Spin Column by pipetting.
6. Centrifuge 1 min. Discard the flow-through.
7. Add 500µL Buffer PB and centrifuge 1 min. Discard the flow-through.
8. Add 400µL Buffer PE and centrifuge 1 min. Discard the flow-through.
9. Repeat step8.
10. Centrifuge 1 min additionally.
11. Replace the QIAprep Spin Column in a eppendorf tube. Let stand for 1 min.
12. Add 50µL Buffer EB. Let stand for 1 min.
13. Centrifuge 1 min. The flow-through is plasmid DNA solution.


■Genome DNA Purification; Generation™ Capture Column (QIAGEN)


1. Add 200µL overnight cultures of E. coli in LB medium to the Capture Column.
2. Incubate 1 min at room temperature.
3. Add 400µL DNA Purification Solution 1, incubate 1 min at room temperature.
4. Centrifuge 10 s with tabletop centrifuge.
5. Transfer the Capture Column to the Waste Collection Tube.
6. Add 400µL DNA Purification Solution 1, incubate 1 min at room temperature.
7. Centrifuge 10 s with tabletop centrifuge.
8. Add 200µl DNA Elution Solution 2. (Don't incubate.)
9. Centrifuge 10 s with tabletop centrifuge.
10. Transfer the Capture Column to DNA Collection Tube.
11. Add 100µl DNA Elution Solution 2, incuvate 10 min at 99℃ with heat block.
12. Centrifuge 20 s with tabletop centrifuge. Purified DNA will be released to solution.
