You should make use of the calendar feature on the wiki and start a lab notebook. This may be looked at by the judges to see how your work progressed throughout the summer. It is a very useful organizational tool as well. |
Lab Protocols
Competent Cell with Calcium Chloride
Materials
- Solid LB medium - 1 plate
- Liquid LB medium
- 2 250ml centrifuge tubes
- Centrifuge
- Cell sample (DH5-alpha in our case)
- Autoclave
- Inoculation loop
- Liquid nitrogen
- 37°C oven
- CaCl2:
- 60mM CaCl2
- 10mM HEPES
- 15% glicerol
- H2O to 100ml
Methods
- Risk the LB plate with the cell sample (DH5-alpha)
- Incubate the plate at 37°C overnight
- Sterilize in the Autoclave
- 100ml of liquid LB medium
- 100 ml of CaCl2
- 2 250ml centrifuge tubes
- Prepare a 6ml LB inoculum with a DH5-alpha colony and incubate at 37°C/250rpm overnight
- Add 2ml of the inoculum in 100ml of liquid LB medium. Incubate at 37°C/250rpm until the OD reaches 0,375
- Distribute the volume in 2 250ml centrifuge tubes (pre chilled) and spin at 10000rpm/7min/4°C
- Discard the supernatant and ressuspend the pellet in 10ml of CaCl2 solution
- Spin the tubes at 7000rpm/7min/4°C
- Discard the supernatant and ressuspend the pellet in 10ml of CaCl2 solution. Incubate 30min on ice
- Spin at 7000rpm/7min/4°C
- Discard the supernatant and ressuspend the pellet in 2ml of the CaCl2 solution
- Distribute the 2ml in 500ul tubes adding 50ul in each.
- Freeze the samples in liquid nitrogen
- Stock at -80°C
Day 1
Day 2
Day 3
Transformation in Escherichia coli (DH5-alpha)
Materials
- 1,5ml tube
- Styrofoam box with ice
- Agar plate with antibiotic
- Competent cells
- Plasmidial DNA
- Centrifuge
- Water bath at 42°C
- Liquid LB medium
- Shaker
Methods
- Briefly spin the competent cells and put then on ice
- Add 50ng of plasmidial DNA in a 1,5ml tube
- Add the 50ul of competent cell in the same tube
- Keep the tube on ice for 25min
- Put the tube in a 42° water bath for 2 min
- Put the tube on ice for 5 min
- Add 200ul of liquid LB
- Incubate at 250rpm/37°C/1 hour
- Plate the the solution in a Agar plate with the appropriate antibiotic
- Incubate the plate at 37°C overnight
