Materials:
- Pipettes + Pipette tips
- Eppendorf tubes
- Greiner tubes
- Centrikon or a similar ultracentrifuge + all additional equipment
Procedure
- Cut the knot of the dialysis tubing and empty the content into a clean 50 mL Greiner tube
- Prepare a Centrikon T-1055 ultra-centrifugation vessel and use a TFT 65.13 rotor, fill the vails with 4 ml of the sample
- Gently put 4 mL of a 20% Sucrose in demiwater solution under the 4 mL sample
- Balance the vails with reassembly buffer
- Centrifuge at 45000 rpm for 3 h, remember the orientation of the vessel so you know where to look for the pellet
- Take a sample from the supernatant (for Western blotting) and decant the rest (supernatant also contains single subunits)
- A transparent pellet should be visible
- Resuspend/ dissolve the pellet in 200 uL of Formation Buffer
