thin sec·tion

, ultrathin section
a section of tissue for electron microscopic examination; the specimen is fixed, typically in glutaraldehyde and/or in osmium tetroxide, embedded in a plastic resin, and sectioned at less than 0.1 mcm in thickness with a glass or diamond knife in an ultramicrotome.

We examined ultrathin sections of RBCs incubated with gold particles in a Philips 300 TEM at 60 kV (Philips, Zurich, Switzerland).
Transmission electron microscopy of ultrathin sections gave good intracellular information but was not able to give a gross morphologic landscape of the infected cells.
Ultrathin sections were cut on a Reichert-Leica Ultracut S ultramicrotome and examined in a Philips 201 electron microscope at 60 kV.
After preparing ultrathin sections with an LKB-ultratom III (LKB Instrument, Rockville, MD, USA) and treating them with uranyl acetate and lead citrate, we examined samples using a TEM (EM 902A; Zeiss, Oberkochen, Germany).
One-micrometer-thick sections, stained with toluidine blue and with methylene blue-azure II/basic fuchsin, were scanned to select appropriate areas for ultrathin sections.

The ultrathin sections of infected Vero cells were observed through transmission electron microscopy (Hitachi H7000).
Ultrathin sections were stained in ethanolic uranyl acetate and lead citrate and examined by electron microscopy (JEM-200 FX; JEOL, Tokyo Japan).
