4uL of a 6uM MT solution in BRB80 (80mM PIPES, 2mM MgCl2, 1mM EGTA pH 6.8) along with 20uM paclitaxel was added onto a plasma-cleaned grid. The MTs were incubated for 1 minute at room temperature, and then the excess liquid was removed from the grid using Whatman #1 paper. Next, 4uL of a solution containing 17.5uM KIF1A-R350W in BRB80 supplemented with 20uM paclitaxel and 5mM AMP-PNP was added to the grid. The grid with the MT and kinesin mixture was then mounted into a Vitrobot, incubated for 1 minute at room temperature, and plunge-frozen into liquid nitrogen-cooled ethane..
