LB medium
(Estimated time: 10 min + 4 hours of autoclavation and cooling)
Materials needed:
- NaCl
- BactoTryptone
- Yeast extract
- ddH2O
- Agar
- Clean bottle or E-flask
- For a final volume of 1 l, put:
- 10 g NaCl
- 10 g BactoTryptone
- 5 g Yeast extract
- 15 g Agar (only for LB plates)
- into 1 l of ddH2O.
- Autoclave the solution.
- Let it cool to ~40-45°C
- Add the proper antibiotic if needed.
- ONLY FOR PLATES:
- Pour an homogenous layer of agar LB into Petri plates under the hood.
- Let agar LB polymerase.
- Cover and store at +4°C.
- Always check for contaminations before using!
