Growth and Isolation
1. Grow 1–5 ml bacterial culture overnight or
16 hr.
2. Measure A
600
(if higher yield required).
3. Transfer an appropriate volume of culture to
a capped 2 ml tube. Centrifuge and
decant supernatant.
4. Add 250 µl resuspension solution; vortex.
5. Add 250 µl lysis solution; invert 6–8x.
6. Add 350 µl neutralization solution; invert 6–8x.
7. Centrifuge 5 min to pellet cell debris.
Purification
8. Transfer cleared lysate (supernatant) to
mini spin/vac column.
9. Centrifuge 1 min to bind plasmid DNA.
Decant flow-through.
10. Add 750 µl wash solution and
centrifuge 1 min. Decant flow-through.
11. Centrifuge additional 1 min to remove
residual wash solution.
Collection of Purified Samples
12. Transfer mini spin/vac column to a clean
1.5–2.0 ml capped tube.
13. Add 50 µl elution solution. Let stand 1 min
and then centrifuge 1 min to elute.
14. Purified DNA is ready to use or can be
stored at 4°C.
