Making LB for plates
br/>
To make 1 Liter of LB:
1. Always use a 10:5:5 ratio of Tryptone to Yeast Extract to NaCl.
2. Add dry ingredients first.
3. Use a 2L flask.
- Add the following
- 10 g Tryptone
- 5 g Yeast Extract
- 5 g NaCl
- 1.5 g Agar (NOT agarose!)
4. Then add 1 L of MilliQ water.
5. Autoclave by total volume.
6. Pour 25 mL on each plate (just enough to cover the bottom).
Making Liquid Media
br/>
Always use a 5-2.5-2.5 ratio of Tryptone to Yeast Extract to NaCl
Add dry ingredients first, then add MilliQ water
No Agar!
Autoclave by total volume
Making Glycerol Stock
br/>
To make 400 mL of 10% glycerol you will need:
-40 mL glycerol
-360 mL of MilliQ water
To make 400 mL of 20% glycerol you will need:
-80 mL glycerol
-320 mL of MilliQ water
1. Use flasks and bottles before graduated cylinders (they take forever to mix!)
2. Need a stir plate and a large stir bar
3. Stir until mixture is homogeneous
4. Don’t autoclave!
Making ddH2O
br/>
- Use the small bottles.
- Autoclave water by total volume.
Autoclaving
br/>
- Robert is the source of official help on all things about the Autoclave.
1. Look at the Betastar for settings.
2. Go by materials and total volume.
Use the autoclave tape and make sure it has changed colour by the end of the cycle.
Ligation
br/>
- We used the
Ginkgo bioworks protocol
- Control: 2 uL of Circular PSB1C3 plasmid, 13 uL ddH2O, 2 uL T4 ligase buffer, 1 uL T4 ligase
- P&C: 2 uL of Circular PSB1C3 plasmid, 2 uL of PUF, 11 uL ddH2O, 2 uL T4 ligase buffer, 1 uL T4 ligase
- L&P: 2 uL of linear PSB1C3 plasmid, 2 uL of PUF, 11 uL ddH2O, 2 uL T4 ligase buffer, 1 uL T4 ligase
