Glycerol Stock

What you will need:

• Overnight with bacterial growth
• Screw cap tubes
• Glycerol

Preparation:

1. Prepare X 1.5 microcentrifuge tubes, where X is the number of constructs to be made.
2. The beads are stored at 4ºC, vortex briefly to resuspend the beads and dispense 40 μL into each tube. Return the stock of beads to 4ºC immediately.
3. Apply the magnet, wait until solution clears completely, aspirate supernatant.
4. Wash beads by adding 75 μL of “Wash/Binding Buffer” and resuspend by flicking.
5. Apply the magnet, wait until solution clears completely, aspirate supernatant.
6. Repeat steps 4 & 5 once more.

• Pipet 150 uL 50% glycerol into 3* properly labeled 1.5 ml screw cap tubes.
• Add 350 uL of overnight culture to each tube.
• Pipet up and down to gently mix.
• Flash freeze in liquid N2 or dry ice/methanol bath
• Place in -80 C freezer when frozen.
