(19) After thin-layer chromatography on high-performance thin-layer chromatographic plates with two different solvent mixtures, zeranol, estradiol, estriol and estrone are analysed as azo dyestuffs.
(20) As a second part of the strategy, the paper addresses more general questions relating to the ultimate fate of dyestuffs when discharged in aqueous effluents and in particular considers their most likely environmental distribution, their potential for bioaccumulation, and their biodegradability.
Thionine
Definition:
(n.) An artificial red or violet dyestuff consisting of a complex sulphur derivative of certain aromatic diamines, and obtained as a dark crystalline powder; -- called also phenylene violet.
Example Sentences:
(1) CIN III nuclei in CS and PEC specimen were Thionin-Feulgen stained and digitized.
(2) It involves the selective staining by the thiazine dye thionine and the interpretations were facilitated by a preceding primary alkylamine O-deacylation step.
(3) On optical analysis, the thiazin dye molecules (azure B, AZURE C and Thionin) are bound radially on the membrane.
(4) The author describes the morphology and distribution of the neurosecretory cells in the supraoesophageal ganglion of the adult female Culex pipiens molestus, using paraldehyde fuchsin and paraldehyde thionine-paraldehyde fuchsin as vital staining techniques.
(5) In attempts to evaluate immunocytochemically autopsy and biopsy material previously obtained and processed for conventional histologic staining, we had to resort to immunostaining of tissues embedded years ago or even sections already stained with hematoxylin-eosin or aldehyde thionin-PAS-orange G. Hypophysial growth hormone and prolactin proved remarkably resistant to such prior treatment with regard to their antigenic properties, and could be readily immunostained in tissue embedded in paraffin 3-4 years earlier, and after destaining of sections prepared up to 7 years earlier.
(6) frequently causes damage to sections and gives inconsistent results because of insufficient primary oxidation and difficulties in making the thionin-Schiff reagent.
(7) In mature light-adapted barley plants, mRNA encoding leaf-specific thionins may reaccumulate if these plants are exposed to pathogens or other stresses.
(8) The enzyme is also sensitive to externally added thionins when expressed in the cytoplasmic compartment of tobacco protoplasts transformed with the Gus gene under the 35S promoter of the cauliflower mosaic virus.
