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. ...

High resolution image of the nucleoli of the macronucleus. Nucleoli have a core of DNA that contains the genes that are transcribed into ribosomal RNA. Assembly of the ribosomal subunits from this pro...

Transmission electron micrograph showing the nucleus of a mouse cardiac tissue with nucleolus. At the center of the image is a large structure called the nucleus which is a membrane-limited compartmen...

The division furrow of a dividing Didinium. A thick layer of epiplasm coated on the cytosolic side by mitochondria forms the constricting ring in the furrow. As usual mucocysts lie between the epiplas...

Transmission electron micrograph of section through the macronucleus of Nassula sp containing many darkly staining nucleoli.

Transmission electron micrograph of a section of a human polymorphonuclear neutrophil from circulating blood. Neutrophil nuclei are often lobed, as seen in the electron micrograph and light micrograph...

3T3 cells, 5min after the induction of DNA damage by microirradiation with a 405 laser. Cells were immunostained with antibody against H3K9me3 (green), a post-translational histone modification enric...

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...

chicken erythrocyte nuclei were allowed to decondense in a low salt high pH buffer, fixed with HCOH, centrifuged onto a carbon coated EM grid, and stained with uranyl acetate. (Spreading technique of ...

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...
