Diagnosis of amyloid beyond Congo red
Current Opinion in Nephrology & Hypertension, 2020Purpose of review Amyloidoses are a group of rare and heterogeneous diseases in which abnormally folded proteins deposit in tissues and lead to organ damage. A brief review of advances in the diagnosis of extracerebral systemic amyloidoses in the context of recent advances in their clinical management is provided.

Sonochemical degradation of Congo Red
International Journal of Environment and Waste Management, 2008Ultrasound irradiation was found to be effective in treatment of refractory pollutants. The present communication reports ultrasound treatment of Congo Red (CR). The CR degradation by ultrasonic waves (50 kHz) was investigated at 25?C. After sonication for 60 min, the CR concentration gradually decreased from 100 mg/L to 27.7 mg/L.

The congo red stain revisited.
Annals of clinical and laboratory science, 1989The Congo red stain has undergone several modifications since it was first used by Bennhold in 1922 in order to increase the specificity for staining amyloid. Most of the laboratories in the United States use the method of Puchtler which uses alkaline Congo red solution. Some of the variables associated with the procedure were investigated by us.

Congo Red-Sirius Red Technique For Amyloid
Laboratory Medicine, 1985A staining technique combining Congo red and Sirius red is described for demonstrating amyloid in plastic-embedded tissue using high-resolution light microscopy. With this combination stain, amyloid stains brighter and with better contrast than is seen with methods that employ Congo red as the only dye.

Quirks of dye nomenclature. 2. Congo red
Biotechnic & Histochemistry, 2014The history, origin, identity, chemistry and uses of Congo red are described. Originally patented in 1884, Congo red soon found applications in dyeing cotton, as a pH indicator for chemists and as a biological stain. Unlike the majority of the 19th century synthetic dyes, it still is available commercially.
