Dipping red litmus paper in the red solution will turn it blue, while dipping blue litmus paper in the blue solution will turn it red. This property gives Congo red a metachromatic property as a dye, both in strongly acidic solutions and with strongly acidophilic tissue. Congo red has a propensity to aggregate in aqueous and organic solutions.
To date, 37 human proteins have been found to form amyloid in pathology and be associated with well-defined diseases. [2] The International Society of Amyloidosis classifies amyloid fibrils and their associated diseases based upon associated proteins (for example ATTR is the group of diseases and associated fibrils formed by TTR).

Structure of thioflavin T bound to an amyloid-like oligomer of β2 microglobulin (in gray), in a complex that displays enhanced and red shifted fluorescence. Many factors that shift the excited state charge from the dimethylaminobenzyl portion of thioflavin T (in blue) to the benzothiazole portion (in red), including binding to rigid, highly ...
Diagnosis of amyloidosis generally requires tissue biopsy. [2] The biopsy is assessed for evidence of characteristic amyloid deposits. The tissue is treated with various stains. The most useful stain in the diagnosis of amyloid is Congo red, which, combined with polarized light, makes the amyloid proteins appear apple-green on microscopy.
The U.N., many Western governments and the DRC all accuse Rwanda's government of backing M23 in a bid to control and exploit their much larger eastern neighbor's vast mineral resources, in an ...

The decades-old conflict in Congo’s mineral-rich east has “drastically deteriorated” since early 2022, and gotten even worse since last October, with sharp increases in sexual violence, the ...
