The Uses of Thioflavine T

A dye used to visualize beta-amyloid plaques, like those associated with Alzheimer's Disease

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.

What are the applications of Application

Thioflavin T is a cell-permeable dye capable of binding amyloid fibrils

Definition

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.

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.
