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.

(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.
