Plasmid Isolation using a Roche KitABSTRACT
The cultures used grow only for 2 and a half hours to avoid the excess of cell mass and polysaccharides that contaminate the samples. We did an electrophoresis gel to see the integrity of the plasmid: Lanes: 1. Ladder 10 Kb. 2. Pablo isolation 1. 3. Pablo isolation 2. 4. My isolation 1. 5. My isolation 2. 6. Ladder 10 kb. As you see the plasmid is very clean, but the samples are at very low concentration. One possible explanation for this is that we perform centrifugations at 13000rpm and not 13000g in the filtration steps, so maybe we lose some DNA in the process. Pablo performed a test digestion to see if ApaI enzyme is cutting the DNA. If you want to see this experiment go to the following link: Digestion test GARDENING
