Day 1

- inoculate 5 ml sterile LB medium (+ antibiotic ?) with single bacterial colony
- grow ON @ 37˚C while shaking vigorously

Day 2

- spin 1.5 ml 2’ @ 8,000 rpm in table top centrifuge
- resuspend pellet in 100 μl P1 Buffer. Let sit 5’ @ RT
- add 200 μl P2 Buffer, mix and let sit no more than 5’ @ RT
- add 150 μl ice cold P3 Buffer, mix well and place 5 – 10’ on ice
- spin 10’ @ max rpm (4˚C if possible)
- transfer supernatant to new tube and add 2 volumes of abs EtOH. Let sit for 10 – 20’ on ice
- spin 10’ @ max. speed @ 4˚C
- discard supernatant and wash pellet with 1ml of 70% EtOH
- spin 5’ @ max speed
- suck up or decant supernatant, speedvac or dry pellet @ 37˚C (do not overdo it, though, or it will not properly dissolve again)
- resuspend pellet in 30 μl TE Buffer or ddH20 and check on gel

note: plasmids obtained with this protocol are not clean enough for sequencing

BioCoder version

Following is the Kafatos:Minipreps protocol in BioCoder, a high-level programming language for expressing biology protocols. What you see here is the auto-generated text ouput of the protocol that was coded up in BioCoder (see Source code). More information about BioCoder can be found on my home page.
