Interphase and metaphase chromosomes have been isolated by spreading unfixed cells on
the Langmuir trough, followed by critical point drying. Both types of chromosomes prove to …

A study of the ultrastructure of interphase chromosomes of frog erythrocytes and human
leucocytes suggested that the 500, 250 and 100 Å microfibrils observed in different …

Electron microscopy of HeLa metaphase nucleoids (ie whole metaphase cells exposed to 2
M salt and non-ionic detergent) spread by the Kleinschmidt technique, reveals a variety of …

When chromosome preparations made by the conventional air-drying method were
processed with the OsO 4/TCH technique and examined by scanning electron microscopy …

Nucleoids obtained from metaphase-arrested HeLa cells by gentle lysis in non-ionic
detergent and 2 M salt were prepared for electron microscopy by Kleinschmidt spreading …

Human chromosomes and their fibers were studied by electron microscopy as whole mounts
in metaphase and interphase after surface spreading and critical point drying and as thin …

Metaphase chromosomes released from cells in the presence of Joklik's suspension media
by vortex-mixing with 0.5 mm glass beads have been analyzed by electron microscopy. In …

Electron micrographs of thin sections of metaphase chromosomes isolated from HeLa ceils
provide new insight into the higher-order arrangement of the nucleoprotein fiber …

Chromosomes have been isolated directly from cells in metaphase for study under the
electron microscope by spreading on a Langmuir trough, followed by critical point drying …

Nuclei and chromosome fibers isolated from the amphibians Triturus viridescens and Rana
pipiens, and the milkweed bug, Oncopeltus fasciatus, by the Langmuir trough—critical point …
