Nucleated erythrocytes from chicken were spread on water, the dispersed chromatin picked up on carbon-formvar grids, fixed with paraformaldehye, critical point dried and shadowed with platinum. Image...

The nucleolus during mammary epithelial differentiation and early mammary tumorigenesis. Proliferating 3D cultures of MCF-10.B2 cells at day 20 were stained with ANA-N antibody to detect nucleoli (gre...

Avian erythrocytes differ from most vertebrates in retaining the nucleus at maturity. During erythrocyte development, transcription is progressively shut down and nuclei become compact and heterochrom...

X-ray analysis shows that the nucleated erythrocytes of the amphibian Necturus maculosus (Mud Puppy) contains more ordered chromatin than most nuclei. Here, chromatin fibers were isolated from N. mac...

Phosphorus has a characteristic electron energy loss with an edge at 160 eV. The Zeiss 902 electron microscope permits images to be recorded at different energy losses which can be digitized and proce...

A drop of a preparation of chicken erythrocyte nuclei was exposed to low ionic strength and centrifuged onto a formvar-carbon film, fixed with paraformaldehyde and negatively stained with sodium phosp...
