Silver staining of nucleolar granules in tumor cells.
With the aid of a simple silver-staining procedure, large numbers and unusual arrays of nucleolar argyrophilic granules were found in Novikoff hepatoma, KB, and HeLa cells. Some of these arrays consisted of linearly arranged discrete granules, and others were in two to three rows each containing three to five granules. Corresponding formations were not found in either the normal or regenerating...
متن کاملDithizone Staining of Intracellular Zinc: An Unexpected and Versatile Counterscreen for Auxotrophic Marker Genes in Saccharomyces cerevisiae
Auxotrophic marker genes such as URA3, LEU2, and HIS3 in Saccharomyces cerevisiae have long been used to select cells that have been successfully transformed with recombinant DNA. A longstanding challenge in working with these genes is that counterselection procedures are often lacking. This paper describes the unexpected discovery of a simple plate assay that imparts a bright red stain to cell...
متن کاملBrief report Detection of tryptase in cytoplasmic granules of basophils in patients with chronic myeloid leukemia and other myeloid neoplasms
Tryptases are serine proteases primarily expressed in mast cells. Normal blood basophils express only trace amounts of the enzyme. However, recent immunohistochemical studies have raised the possibility that neoplastic basophils express significant amounts of tryptase. In this study, tryptase expression was analyzed in normal and neoplastic basophils by immunoelectron microscopy using antitrypt...

متن کاملSimple Detection of Mercury Ion Using Dithizone Nanoloaded Membrane
The simple Hg(II)-detection system was studied and developed using dithizone nanofiber loaded membrane. Dithizone is one of the most frequently used chemical substances for Hg(II) ions extraction in water. Hg(II)-dithizone complex substance [Hg(HDith)2] is stable in acidic condition and, presenting with the orange-brown color. To prepare dithizone nanoloaded membrane, dithizone solution (in ace...
