In 1959, Vassar and Culling first employed Thioflavin T (ThT) for the fluorescence imaging of amyloid plaques, revealing its potential for histological staining. In 1993, LeVine standardized the method for quantifying fibril formation using ThT, providing a simple fluorescence-based approach for studying protein folding and aggregation kinetics[1].

??

Textile dyeing, fluorescent sign paints, in combination with green or blue pigments to produce brilliant greens, phosphotungstic pigments.

?? ??

Upon binding to amyloid fibrils, Thioflavin T (ThT) exhibits a significant increase in fluorescence intensity, making it a common tool in research on protein aggregation-related diseases such as Alzheimer's disease and Parkinson's disease. The figure below shows the result of ThT staining[3].
Thioflavin T staining

?? ??

4-(6-Methyl-2,3-dihydrobenzo[d]thiazol-2-yl)benzenaminewith methanol and hydrochloric acid or sulfuric acid, at 160 ~ 170 ℃ methylation under pressure.

?? ??

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.

Purification Methods

Crystallise the chloride from *benzene/EtOH (1:1). [Beilstein 27 III/IV 5052.]
