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.

To further understand the pathogenic changes of the diseased crab, the ultrathin sections of tissues of the diseased crab sampled from the farms were examined with transmission electron microscopy.
Ultrathin sections (>100nm) were made with a diamond knife, collected on copper grids (300 mesh) previously coated with formvar film, post-contrasted with aqueous solutions of 2% uranyl acetate and 3% lead citrate for 3min on each, and washed with distilled water.
We examined ultrathin sections of RBCs incubated with gold particles in a Philips 300 TEM at 60 kV (Philips, Zurich, Switzerland).
Ultrathin sections were made with a Leica ultramicrotome and stained with uranyl acetate and lead citrate (Reynolds 1963).
The ultrathin sections were stained with lead citrate and uranyl acetate and examined with a Philips CM100 transmission electron microscope.
We have two tests for lignin: 1) sectioned specimens are stained with acriflavin and viewed with fluorescent confocal microscopy, and 2) ultrathin sections are stained with KMn[O.sub.4] and viewed with transmission electron microscopy (TEM).
Ultrathin sections stained with uranyl acetate-lead citrate were examined with a JEOL 1200 electron microscope (JEOL, Tokyo, Japan).
For TEM observation, the film was cut into ultrathin sections of 70 nm thickness by ultramicrotome (Ultracut N, Reichert-Nissei), and the ultrathin sections were stained by Ru[O.sub.4] (which selectively stains PPE).
The later concept is reinforced by the inclusion of electron photomicrographs of ultrathin sections contributed by Ralph Foster, who pioneered this technology.
In ultrathin sections through the pathologically altered skin tissue of budgerigars, virus particles were present in both nuclei and cytoplasm of epidermal cells, often in crystalline form.
Ultrathin sections were made on a Leica ultramicrotome and the sections were stained with uranyl acetate and lead citrate (Reynolds 1963).
The scanning electron microscopy images showed a holistic view of SARS-CoV--infected cells compared to ultrathin sections in transmission electron microscopy.
