Description

High voltage (1MeV) transmission electron microscopy image of a 0.5 micrometer section through a Chinese hamster ovary cell at metaphase showing a chromatid pair, with kinetochores at the centromere. The image was taken with a specimen tilt of 42 degrees and is one of a group of 10 tilts from 77 degrees to 32 degrees at 5 degree intervals. Pairs of images provide oblique stereo views of the chromosome.

Technical Details

CHO cells at metaphase were fixed with paraformaldehyde followed by OsO4, embedded in epoxy resin and 0.5 micrometer 'thick' sections stained with uranly acetate for HVEM observation. See also: H.
