Figure 3.
Dynein staining at kinetochores 10 min after they have been detached from the spindle. (A and B) Live cell images. A chromosome (arrow) was detached from a metaphase spindle, placed in the cytoplasm, and held there for 10 min. (C) Superimposed phase–contrast and immunofluorescence images. (D) Immunofluorescence image. (E) Composite showing the kinetochores labeled in C at higher magnification. The detached kinetochores (d1 and d2) stain more brightly than the control kinetochores that remained attached (c1–c4). Bars, 10 μm.
