Upon electron bombardment, some elements, such as P, show an electron energy loss profile with a peak at a specific energy loss value. By collecting a series of images of a field at different energy l...

Transmission electron micrograph showing part of a decondensed mitotic chromosome. The residual protein 'scaffold' (at bottom) is surrounded by a 'halo' of DNA loops 20 to 24 micrometers long. The en...

Chicken erythrocyte nuclei were allowed to disperse in low salt, centrifuged through formaldehyde onto an EM grid, stained with uranyl acetate, and examined with the Madison 1MeV TEM at 40 KX in darkf...

High Voltage transmission electron micrograph of human female (HeLa) mitotic chromosomes from metaphase arrested cell swollen in hypotonic medium and recorded at 1 MeV. This image was taken with a sp...

Shown are 0.5 micrometer thick confocal image of midplane sections of synchronized 3T3 fibroblasts pulsed for 2 min with CldU and labeled with FITC (green) followed by a variable chase time, and a sec...

Transmission electron micrograph of unstained cryo-section of a sperm cell of the starfish Patiria miniata. Echinoderm sperm nuclei are unusual in that chromatin fibers are clearly seen, allowing the...

Transmission electron micrograph of isolated HeLa cell metaphase chromosome decondensed by removal of histones with dextran sulfate and heparin, centrifuged onto a carbon film and stained with uranyl ...
