Freezing of bacterial stocks
Materials:
- Bacterial culture
- LB medium
- 80% glycerol
- Centrifuge
Protocol:
1. Take 5 mL bacterial cells from the Erlenmeyer of a freshly grown culture and spin in a 15 mL tube for 10 minutes at 2.000 rpm (Eppendorf centrifuge).
2. Decant the supernatant without disturbing the pellet.
3. Pipet on the pellet 0.5 mL 1% LB medium and 0.5 mL 80% glycerol and mix by vortexing and save in -80 °C freezer.
