描述

一般說明

An amyloidophylic dye that specifically stains stacked β sheet aggre-gates. Useful for staining and visual detection of amyloid deposits in nerve tissue. Binds to amyloid fibrils but not to non-polymerized amyloid peptide. Inhibits the accumulation of the scrapie-associated, protease-resistant isoform of protein PrP without affecting the normal isoform possibly through overstabilization of the conformation. It is also shown to inhibit Pot1 Binding to Telomeric DNA.
