Biological Activity
Direct Red 254 (1% (w/v)) stains amyloid-like synthetic peptides and induces birefringence in vitro: some peptide fragments with amyloid-like properties (e.g., peptide fragment N14) exhibit green birefringence under polarized light after staining. This is a typical characteristic of amyloid deposits[1].
Direct Red 254 can be effectively biodecolorized, and its decolorization efficiency is affected by its molecular structure and aggregation behavior in aqueous solution[2].
