1. 4 eppendorf tube were taken and marked lysis, p-tet, positive and negative.
2. The dry DNA from the DNA Distribution Kit was extracted by mixing each part with 15 micro ml of water using a micro-pipette.
3. 2-3 micro ml of this plasmid solution was then added to 100 micro ml of DH 5-alpha E.Coli cells.
4. The positive and negative marked tubes were also filled with control plasmids.
5. The tubes were incubated in ice for 40 minutes, then given a heat shock for 30 seconds @ 42 degrees Celsius and then put in ice for 2-5 minutes.
6. They were mixed with 330 micro ml LB (Luria Bertani).
7. Left to grow for approximately an hour @ 37 degrees Celsius in the shaker.
8. Centrifuged at room temperature for 3 minutes @ 8000 rpm.
9. Discard 900 micro ml of the super-natured solution and dissolve pellets in remaining 100 micro ml. These were then spread on LB Agar plates containing 100 micro gram per ml Ampicillin.
10.Plates were incubated at 37 degrees Celsius overnight.
