Extracting our plasmids from our transformed cells
The MiniPrep kit needs 35ml ethanol added to the "Wash Solution" and RNAase 2 added to the "Resuspension Solution", which then needs storing in the fridge.
Method:
- Pipette 1ml of liquid growth culture into each of 3 Eppendorfs (same liquid culture for each)
- Centrifuge at 8,000 rpm for 5 minutes and pour off the supernatant
- Add 250ul resuspension solution to one of the Eppendorfs. Resuspend the pellet, then draw up the contents of this Eppendorf and pipette into the next Eppendorf. Resuspend the pellet in this Eppendorf, then draw up the contents and pipette into the third and final Eppendorf. Resuspend the pellet in this Eppendorf.
- This last Eppendorf is what we use for the rest of the MiniPrep. This is to get the maximum amount of plasmid as possible from the transformed cells.
