Protocol: Making LB Plates
Procedure:
LB Agar (To Make 1L):
- Before you start:
- Use AGAR not agarose!
- Use an Erlenmeyer flask that is twice the volume of your solution (avoid spillage in autoclave).
- Keep your flask on a stir plate with a stir rod.
- Put Aluminum foil on the top of the flask and put autoclave tape on.
- DON`T let it solidify after autoclaving by keeping it on a stir plate while it cools.
- DON`T put tubes of antibiotics back into freezer.
- Add the following to 800 ml MilliQ H20:
| Bacto-tryptone | 10g |
| Yeast extract | 5g |
| NaCl | 10g |
- Adjust pH to 7.5 with NaOH (Optional).
- Add 15g agar.
- Melt agar into solution in the microwave (Optional).
- Adjust volume to 1L with MilliQ H20
- Autoclave on the liquid cycle (no drying time) (aka LIQ20) for 30 minutes.
- Wait for it to cool to touchable temperature and then add antibiotics if necessary. Amount of antibiotic required should be in the protocol binder.
- Pour plates, making sure they are color coded with the type of antibiotic that you used.
Making LB Broth:
- All of the above WITHOUT AGAR.
