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

• 100 ml of CaCl₂
• 2 250ml centrifuge tubes
2. Prepare a 6ml LB inoculum with a DH5-alpha colony and incubate at 37°C/250rpm overnight

Day 3

1. Add 2ml of the inoculum in 100ml of liquid LB medium. Incubate at 37°C/250rpm until the OD reaches 0,375
2. Distribute the volume in 2 250ml centrifuge tubes (pre chilled) and spin at 10000rpm/7min/4°C
3. Discard the supernatant and ressuspend the pellet in 10ml of CaCl₂ solution
4. Spin the tubes at 7000rpm/7min/4°C
5. Discard the supernatant and ressuspend the pellet in 10ml of CaCl₂ solution. Incubate 30min on ice
6. Spin at 7000rpm/7min/4°C
7. Discard the supernatant and ressuspend the pellet in 2ml of the CaCl₂ solution
8. Distribute the 2ml in 500ul tubes adding 50ul in each.
9. Freeze the samples in liquid nitrogen
10. Stock at -80°C

Transformation in Escherichia coli (DH5-alpha)

1. 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

2. Methods

1. Briefly spin the competent cells and put then on ice
2. Add 50ng of plasmidial DNA in a 1,5ml tube
3. Add the 50ul of competent cell in the same tube
4. Keep the tube on ice for 25min
5. Put the tube in a 42° water bath for 2 min
6. Put the tube on ice for 5 min
7. Add 200ul of liquid LB
8. Incubate at 250rpm/37°C/1 hour
9. Plate the the solution in a Agar plate with the appropriate antibiotic
10. Incubate the plate at 37°C overnight

28/07 Assembly AIII: Restriction analysis (+NdeI enzyme) OBS: This analysis was reapeted because we had problems confirming the assembly. The issue was that bot the construction and the pSB1C3 vector had similar size. Check out the Lab Journal report of the day for more information. Assembly AII, AV and AVI: Digestion EXSP	29/07 >Assembly AII, AV and AVI: Gel Purification Ligation	30/07 >Assembly AII, AV and AVI: Transformation	31/07 Assembly AII, AV and AVI: Inoculum PCR BBa_K143055 for RBS removal OBS: This was one of the parts sent by the Imperial College Team. Because of a comunication failure we assumed that this part was comming without the RBS, so we included a RBS in the parts we were going to use with this Lac promotor :) PCR of Plac BBa_K143055 was followed by a Gel Purification and Ligation in the PUC19 vector
