Congo red
Videos
Congo red is an organic compound, the sodium salt of 3,3′-bis. It is an azo dye. Congo red is water-soluble, yielding a red colloidal solution; its solubility is greater in organic solvents. The use o

Amyloid
Videos
Amyloids are aggregates of proteins characterised by a fibrillar morphology of typically 7–13 nm in diameter, a β-sheet secondary structure and ability to be stained by particular dyes, such as Congo

…This aggregation phenomenon is more prevalent in high Congo red concentrations, at high salinity and/or low pH. Diagnostic use Micrograph demonstrating amyloid deposition (red-orange) with Congo red staining in cardiac amyloidosis In histology and microscopy, Congo red is used for staining in amyloidosis, and…
