描述 | Congo Red is an azo dye, and its binding is utilized as a diagnostic test for the presence of amyloid in tissue sections. |
体外研究 | Congo Red histochemical stain may act as a straightforward screening method to determine whether aggregates in mutant cells exhibit misfolded β-pleated sheet secondary structures. It specifically binds to crossed β-pleated sheet structures. While wild-type HSPB1 should preserve protein homeostasis by binding proteins in non-native conformations to prevent aggregation, the T139M mutant fails in this function, leading to an accumulation of misfolded proteins targeted by Congo Red for intercalation between the β-pleated sheet structures[1]. |
