Descrição

Descrição geral

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.

An amyloidophylic dye that specifically stains stacked β sheet aggregates. Useful for staining and visual detection of amyloid deposits. Does not bind to non-polymerized amyloid peptide. Inhibits the accumulation of the scrapie-associated, protease-resistant isoform of protein PrP without affecting the metabolism of the normal isoform. It is also shown to inhibit Pot1 Binding to Telomeric DNA.
