The negative stain
methylamine tungstate tolerates collection of the 140 images typically needed for a tomography series, yielding reconstructions of SV surfaces with exquisite detail.
16) Negative stain
electron microscopy is a useful method for addressing questions concerning size distribution of the liposome, and it is a reliable technique that is simple to perform and requires only limited specialized equipment.
1A), the use of different negative stains
revealed different appearances (Fig.
119) The differential diagnosis of YST from spermatocytic tumor could be further confirmed by immunoreactivity of GPC3 and AFP in YST and negative stain
in spermatocytic tumor.
This finding was quickly corroborated by negative stain
EM, IHC assay, serologic testing, and molecular assays.
A coated grid with sample adsorbed to the surface is floated on a drop of negative stain
Rotavirus infections were diagnosed by negative stain
A negative stain
preparation may be made and a result could be obtained within 5 minutes of the specimen's arrival in the EM laboratory.
The ambiguous group included those with other combinations of stains, including negative stains
for all markers.
