GMPCPP MT seeds in warm BRB80 applied to the grid followed by second application of pre-warmed lysate containing over expressed EML1-GFP. After an incubation time of 20 seconds, grid blotted for 3 seconds before plunging into liquid ethane..
Goat brain tubulin was polymerized with 1mM GMPCPP at 310K for 2 hours, spun on warm 50 percent BRB80 sucrose cushion and resuspended in twice the volume of warm BRB80 buffer
