Chromatin freeze fracture electron microscopy: a comparative study of core particles, chromatin, metaphase chromosomes, and nuclei

J Lepault, S Bram, J Escaig, W Wray - Nucleic Acids Research, 1980 - academic.oup.com
Chromatin gels, metaphase chromosomes, and intact nuclei were studied by freeze
fracturing followed by electron microscopy. The results complement and extend those …

Ultrastructural organization of freeze‐fractured interphase nuclei

NM Maraldi, F Marinelli, A Galanzi, N Zini… - Biology of the …, 1986 - Wiley Online Library
The morphology of intact or membrane‐deprived interphase nuclei has been analysed by
freeze‐fracture electron microscopy. This method appears particularly useful for providing …

Ultrastructural preservation of nuclei and chromatin: improvement with low‐temperature methods

RA Horowitz, PJ Giannasca… - Journal of …, 1990 - Wiley Online Library
The ultrastructure of chromatin has been examined in nuclei prepared by a variety of low‐
temperature methods. Embedding glutaraldehyde (GA)‐fixed nuclei in Lowicryl K4M or …

Morphometric and topologic analysis of freeze-fractured interphase nuclei.

NM Maraldi, F Marinelli, R Ranaldi, S Papa… - Analytical and …, 1986 - europepmc.org

Three‐dimensional view of the chromatin in freeze‐fractured chicken erythrocyte nuclei

GH Haggis, EF Bond - Journal of microscopy, 1979 - Wiley Online Library
The freeze‐fracture thaw‐fix (FfTF) technique described in earlier papers is applied in the
present work to more detailed study of the chicken erythrocyte, by transmission replicas and …

Electron microscopy of chromatin

CL Woodcock, RA Horowitz - Methods, 1997 - Elsevier
Electron microscopy, with its ability to image DNA and nucleosomes, can provide a key
visual link in the understanding of chromatin conformation. We discuss applications of EM to …

Formaldehyde and glutaraldehyde in the fixation of chromatin for electron microscopy

BT Sewell, C Bouloukos, C von Holt - Journal of microscopy, 1984 - Wiley Online Library
Glutaraldehyde and formaldehyde have been used to fix chromatin core particles for
electron microscopy. Glutaraldehyde crosslinks protein only, whereas formaldehyde …

Electron microscope specimen preparation of rat liver chromatin by a modified Miller spreading technique.

P Labhart, T Koller - European journal of cell biology, 1981 - europepmc.org
We describe a modification of the spreading method of Miller and Bakken [17]. Prior to
mounting the samples, the carbon supports used for electron microscopy are coated with …
