        1. Thaw tubulin
        2. Adjust solution to a final buffer concentration equivalent of glycerol PB
        3. Incubate at 37 o C for 30 min.
        4. Layer tubulin onto cushions of BRB80 containing 60% (v/v) glycerol the cushions should fill half a polycarbonate centrifuge tube and be prewarmed to 37 o C
        5. Spin at 80,000 rpm for 20 min. at 37 o C in the TLA-100.3 rotor
        6. Aspirate the supernatant above the cushion
        7. Rinse the cushion interface 2 x"s with water
        8. Aspirate the cushion
        9. Break up pellet in BRB80 pre-chilled to 0 o C using a dounce / homogenizer for a large volume or a P1000 pipette tip for a small volume.
          ~undefined Note be sure to avoid creating bubbles during this step !
        10. Incubate at 0 o C for 15 min. to depolimerize the microtubules
        11. Sediment at 80,000 rpm for 10 min. at 4 o C in the TLA-100.3 rotor
        12. Freeze supernatant in small aliquots using liquid nitrogen and store at -80 o C
          Tubulin is active for at least one year.

        Buffers :
        Glycerol PB:
        80 mM K-Pipes
        5 mM MgCl2
        1 mM EGTA pH 6.8
        1 mM GTP
        33 % (v/v) glycerol

        BRB80: (Brinkley Reassembly Buffer)
        80 mM K-Pipes
        1 mM MgCl2
        1 mM EGTA pH 6.8
