Materials:

  • Pipettes + Pipette tips
  • Eppendorf tubes
  • Greiner tubes
  • Centrikon or a similar ultracentrifuge + all additional equipment

Procedure

  1. Cut the knot of the dialysis tubing and empty the content into a clean 50 mL Greiner tube
  2. Prepare a Centrikon T-1055 ultra-centrifugation vessel and use a TFT 65.13 rotor, fill the vails with 4 ml of the sample
  3. Gently put 4 mL of a 20% Sucrose in demiwater solution under the 4 mL sample
  4. Balance the vails with reassembly buffer
  5. Centrifuge at 45000 RPM for 3 h, remember the orientation of the vessel so you know where to look for the pellet
  6. Take a sample from the supernatant (for Western blotting) and decant the rest (supernatant also contains single subunits)
  7. A transparent pellet should be visible
  8. Resuspend / dissolve the pellet in 200 uL of Formation Buffer
