Cultivation
Chloramphenicol stock solution
-Solubilize 20 mg mL-1 Chloramphenicol in 100 % Ethanol
-Store at -20 °C
DNA loading buffer
- 50 % (v/v) glycerol
- 1 mM EDTA
- 0.1 % (w/v) bromphenol blue
- Solve in ddH2O
LB medium
- 10 g Trypton
- 5 g yeast extract
- 10 g NaCl
- 12 g Agar-Agar (for plates)
- Adjust pH to 7.4
M9 medium
For 1 L M9 mineral medium you need 867 mL sterile water (for plates add 16 g Agar-Agar as well). Then add (in the following order:
- 300 µL 1 M CaCl2
- 100 mL 5x M9 salt solution
| 10x M9 salt solution | |
|---|---|
| Na2HPO4-2H2O | 75.2 g/L |
| KH2PO4 | 30 g/L |
| NaCl | 5 g/L |
| NH4Cl | 5 g/L |
- 20 % glucose
| 20 % Glucose | 20 % (w/v)glucose | 200 g/L |
For 500 mL stock solution add 100 g glucose to 440 mL water. Autoclave for 15 at 121° C
- 1 M MgSO4
- 1 mL biotin (1 mg/mL)
- 1 mL thiamin (1 mg/mL)
- 10 mL 100x trace elements solution
TAE buffer
For 1 L of 50 x TAE buffer you need:
- 242.48 g Tris
- 41.02 g Sodiumacetate
- 18.612 g EDTA
- Adjust pH to 7.8 with acetic acid
- Solve in dH2O
10 mL of the stock is diluted in 1 L dH2O for the gel electrophoresis (0.5 x TAE buffer)
