Nuclear DNA was prepared from synchronously replicating nuclei of Physarum polycephalum, mixed with cytochrome c and formamide, and spread on the surface of a hypophase consisting of 10 mM Tris, 1 mM ...

The image shows mitotic metaphase (upper) and anaphase (lower) in Drosophila tissue culture cells immunostained for the microtubule severing protein katanin (green), microtubules (red) and kinetochore...

Radial glial cell from right tectal lobe of Xenopus laevis tadpole CNS, stage 47. This radial glial cell expresses eGFP. It was transfected ~60 hours earlier with in vivo electroporation of plasmid DN...

Dividing egg of the jellyfish (Spirocodon saltatrix showing birefringent spindles. The arrow indicates the direction of the compensator slow axis. AS the cell is rotated 90 degrees with respect to the...

Transmission EM of cotyledons of wildtype Arabidopsis thaliana grown in the dark showing the characteristic quasi-crystalline prolamellar bodies. Other images in this group show the development of typ...

Transmission EM of cotyledons of wildtype Arabidopsis thaliana grown under a normal day/night light regime show the typical chloroplasts with thylakoid membranes organized as stacked grana and non-sta...

Transmission EM of cotyledons of the double knockout oep16.1/16.4 of Arabidopsis thaliana grown in the dark and then exposed to light for 16 hr. The development of characteristic wildtype thylakoids ...

Images of negatively stained chromatin fibers prepared from tandem arrays of a nucleosome positioning sequence reconstituted with purified histones. These samples contained 61 repeats of a 197 bp DNA ...

Distribution of Nup85 (a component of the Nup107-160 nucleoporin complex, red) and CENP-B (kinetochores, green) in dividing Hela cells. See Fig 2B in Orjalo et al. 2006 Mol Biol Cell 17:3806-3818.

Nup160 and Nup96 (components of the Nup107-160 nucleoporin complex) localize at spindle poles during mitosis in HeLa cells whereas Nup93 and Nup62 (nucleoporins absent from the Nup107-160 complex)do n...
