Aim:
- Transformation of new (super)parts
- Incubation
Materials:
•TE Buffer
•Plasmids from Kit Plates 1: R0040; Q04400
•Competent E.coli
•NZY Medium
•Ampicllin, Kanamycin Agar Plates
•Eppendorf (labelled)
Methods:
- Tranformation Protocol 2:
- Using the puch tool, puch out the appropriate DNA. Clean the tool between punches.
- Soak the spots in 5µL of TE that has been warmed to 50ºC for 20 minutes. At this time take the competent cells from the -80º freezer and start defrosting on ice.
- Add 2µL of DNA in TE to 50µL of competent cells (TOP10)
- Allow the DNA and competent cells to sit on ice for 30 minutes
- Heat shock at 42ºC for 60 sec in water bath.
- Recover on ice for 5 min.
- Add 300 µL NZY medium.
- Incubate at 37ºC for 2 hr while the tubes are rotating.
- Centrifuge and leave about 250 µL liquid; hence, resuspend the E.coli suspension.
- Plate 100µL on an LB plate with the appropriate antibiotic.
- Incubation:
- Pick new colonies from plate 15 & 16.
- Incubate with shaking overnight.
