The company ranks among the world's leading producers and providers of products such as 1,2,4-triazole, chloroformates and toluidine
Since abnormal chromatin integrity is more frequent in infertile men than fertile men, some techniques have been developed to evaluate sperm chromatin integrity status referred as cytochemical assays including aniline blue (AB) and toluidine
blue (TB) staining tests (15-17).
The sections were stained with toluidine
blue (1 %), a dye specific for lipid-rich structures, such as the myelin sheath.
Vital tissue staining, commercially marketed as toluidine
blue staining, methylene blue staining, Rose Bengal staining and Lugol's iodine staining, each use their own dye to stain abnormal tissues in the mouth.
cupressoides using Fourier Transform Infrared spectroscopy experiment and combination of agarose/polyacrylamide gel electrophoresis and sequential staining with toluidine
Gligor and Walcarius developed a GCE modified with poly(Toluidine
Blue O) and single-walled carbon nanotubes for amperometric determination of nitrite as electrochemical sensor.
Recently used methylene blue and toluidine
blue as photoactive agents were shown to cause discoloration of anterior teeth (12,16).
For the histological evaluation, all sample slices were carried out by hematoxylin and eosin staining and toluidine
blue staining for histological observation using an Olympus biological microscope (OLYMPUS BH-2, Tokyo, Japan).
Thick sections were taken with LKB 11.800 pyramitome, and stained with toluidine
blue for light microscopic examinations.
Types of pigments: Blacks (carbon black), Blues (phthalocyanine), Greens (phthalocyanine), Reds (bon reds/ maroon, lithol rubine, napthol red, perylene maroon, quinacridane red, quinacridane violet, red lake c, toluidine
red), Yellow and oranges
The stains corresponded to: hematoxylin and eosin, for general histology analysis; Alcian blue, Toluidine
blue and Masson's trichrome, to identify ECGs cells and characterize the content of their granules, and performic acid and Schiff reagent (PAS), to detect mucopolysaccharides.
The different reagents used in Auramine O staining technique were 0.3% Auramine O , 1% acid alcohol as decolorizer and various counter stains like 0.1% potassium permanganate, 0.1% methylene blue, 0.1% toluidine
blue, 0.1% malachite green and undiluted blue ink (9).
