Video-Enhanced Differential Interference Contrast microscopy showing a Klp6₄₄₀His coated bead moving along a taxol-stabilised pig brain microtubule adsorbed to a coverslip. Bead velocity was 47±7 nm s⁻¹ (5) (mean ± SEM (n)) during translocation. At the microtubule tip (dashed line) the bead dwelled for several seconds before detaching. Time (minutes : seconds), scale bar:1 µm.
