241) However, desmoid tumors typically show nuclear [beta]-catenin staining, which is absent in GISTs, and
negative staining for DOG1.
In the present study, only two cases of dysgerminoma showed
negative staining for OCT-4.
2012)
Negative staining of lipopolysaccharides on polyacrylamide gels by using eosin B.
1) to compare sensitivity of
negative staining techniques using various stains such as malachite green, crystal violet, and methylene blue for rapid detection of oocysts of Cryptosporidium, Cyclospora, and Cystoisospora;
In all effusion smears, mesothelial cells revealed
negative staining for CEA.
One case diagnosed as T-cell lymphoblastic lymphoma which showed positivity for CD 99 but showed
negative staining to vimentin hence the possibility of EWS/PNET was eliminated.
Negative staining theoretically replaces water in the interstices of the object until all hydrated volumes are filled with stain, thus forming a uniformly thin, amorphous film in which the specimen is supported and preserved.
With the fluorochrome DAPI, this same pair showed
negative staining (Figure.
Figure 4 is the digital histogram interpretation of P2 population (see Figure 2) showing
negative staining of all events.
In addition,
negative staining can also provide information on whether liposomes produced in a particular manner are multi- or unilamellar.
Electron microscopy with
negative staining of aqueous lysates of the affected skin and of bleeding quills showed isolated or clustered polyomavirus particles 45-50 nm in size.
We did this by evaluating different EM preparation techniques [standard
negative staining, ultracentrifugation (UC) before EM, and immune-specific particle enrichment] and then comparing the best of these EM assays with an up-to-date real-time PCR assay on 531 clinical samples.
