13 protofilament paclitaxel stabilised GDP microtubule

Specimen Preperation
Sample Aggregation State FILAMENT
Vitrification Instrument ?
Cryogen Name ETHANE
Sample Vitrification Details Paclitaxel stabilized GDP microtubules were applied to a glow discharged grid, incubated for 30 seconds at room temperature following which excess sample was wicked off. This step was repeated again. Purified P. falciparum kinesin 8B-motor domain was immediately added to the grid, and excess sample was drawn out by pipetting. Kinesin was added again and the grid was transferred to a pre-equilibrated Vitrobot. Excess liquid was blotted off, and the grid was plunge frozen in liquid ethane.
