Fig. 1. Ran associates with the chromosomes. (A) In meiosis-II-metaphase-arrested
Xenopus eggs, double-labeling of Ran by immunofluorescence and
chromosomes by Hoechst dye shows colocalization of Ran and chromosomes. (B)
Microinjected Rh-Ran is associated with the chromosomes in Xenopus
eggs. (C) Microinjected Rh-Ran is associated with chromosomes in mature mouse
eggs. The dark circular region in the egg is the oil drop from the injection.
