Pre-Interlab: Transformation Practice (p. 25, 07/13/18)
Transformations (Samantha)

Heat Shock (Samantha)
- 1-4: 1 minute, 42°C, then 5 minutes on ice + 200 μL LB to each tube
Note: iGEM protocol says 450 ml of SOC, but instead we used 200 μL of LB
Incubations
- 37°C and 220 rpm, during 1 hour (6:03-7:03 pm)
-
Week 4: 16-22
Interlab: Phase 1 and Preparations (p. 26-27, 07/16/18)
SOC medium preparation (NCb BioLabs, Thermo Fisher)
- 2% Tryptone
- 0.5% yeast extract
- 10 mM NaCl
- 2.5 mM KCl
- 10 mM MgCl2
- 10 mM MgSO4

SOB medium preparation
- 2% Tryptone

- 10 mM MgSO4
Buffer CCMB80 1L preparation
- 10 mM KOAc ph 7.0
- 80 mM CaCl2
- 20 mM MnCl2
- 10 mM MgCl2
Growth
- In 200 ml of SOC
Notes: iGEM protocol says 250 ml SOB, instead 200 ml were used
There’s less overnight, so initial absorbance will be less than 0.1
Optical density
- 3:00 pm, 0.3
- 3:52 pm, 0.465
Note: For buffer resuspension, 20 ml were used instead of 80 ml
RFP transformation after 16 hours
- 12 hours: 1-2 colonies, low expression
- 16 hours: 3-4 colonies, medium expression
Second competents batch
- Previous results were successful, so iGEM (buffer CCMB80) protocol will be repeated.
- Absorbance before the first resuspension: 0.482
- Resuspension in 20 ml of buffer
- Absorbance after resuspension: 0.444
