ChEBI: Thioflavine T is an organic chloride salt having 2-[4-(dimethylamino)phenyl]-3,6-dimethyl-1,3-benzothiazol-3-ium as the counterion. It is widely used to visualise and quantify the presence of amyloids, both in vitro and in vivo. It has a role as a fluorochrome, a histological dye and a geroprotector. It contains a thioflavin T cation. | [Preparation]
4-(6-Methyl-2,3-dihydrobenzo[d]thiazol-2-yl)benzenamine?with methanol and hydrochloric acid or sulfuric acid, at 160 ~ 170 ℃ methylation under pressure. | [General Description]
Thioflavin T is a benzothiazole dye that increases in fluorescence upon binding to amyloid. Thioflavin T has been used in histology and for protein characterization. | [Biochem/physiol Actions]
Cell permeable: yes | [storage]
Store at -20°C | [Properties and Applications]
colourful green light yellow. Soluble in cold water, soluble in hot water for yellow, easily soluble in ethanol and yellow, with green fluorescent. The strong sulfuric acid to colorless, a green fluorescent, diluted into light yellow.
