Gold particle drifting movements observed in association with in vitro MT motilities driven by various motors: (A) 14S dynein control: no Mg2+-ATP supplied. Neither MT nor particle move. (B) 14S dynein; (C) 22S dynein; (D) kinesin, all with 1 mM Mg2+-ATP. In B and C, the particle drifts toward the trailing, (−) polarity end. In D the particle drifts away from the leading, (−) polarity end. B-5–1-2 (anti-α-tubulin antibody) was used in all cases.
