Distribution of 1μm polystyrene particles in a self-organised preparation as viewed by their fluorescence. Microtubules were assembled from a solution of 10 mg ml^-1 tubulin and 2 mM GTP at 36°C. This pattern coincides with the microtubule pattern. Individual particles are visible at the higher magnification shown in the inset. The particle distribution was homogenous prior to microtubule self-organisation.
