Whole human female metaphase chromosome from metaphase arrested cell swollen in hypotonic medium and imaged at 1 MeV. This image was taken with a specimen tilt of 45 degrees. Grouped with it is an im...

Distribution of Nup37 and Bub1 on chromosomes assembled in vitro using Xenopus oocyte extracts and treated with (lower panels) or without (lower panels) nocodazole. Chromosomes are stained with DAPI (...

A maximum intensity projection of a Caulobacter crescentus specimen at 0 degree tilt.

The zero degree tilt view of the raw data acquired from an IVEM of a Caulobacter crescentus sample, strain Snc04. This image has been downsampled from the raw data image which can be accessed using t...

The image shows a developing Drosophila spermatid immunostained for caspase activity (green). TRITC-phalloidin is used to label actin (red). Caspase is required in spermiogenesis for the elimination ...

Confocal image of a Xenopus laevis egg imaged at 119 min post fertilization. The embryos are stained for alpha-tubulin (green) and gamma-tubulin (red).

Shown is a 0.5 micrometer thick confocal image of a midplane section of a 3T3 fibroblast pulsed for 5 min with BrdU and immuno-labeled with anti-BrdU antibodies. Replication is confined to discrete si...
