Congo red is a synthetic dye, used for the differential staining of elastic fibers. Congo red histological staining is the gold standard technique for the detection of amyloidosis. It is a dye belongs to a group of azo dyes derived from benzidine and it does not require the application of mordant. Amyloid refers to the abnormal, fibrous extracellular proteinaceous deposits found in organs such as kidney, spleen, liver etc. the deposition of amyloids in the tissue is known as Amyloidosis. In histology, the Congo red is used for staining amyloidosis, other amyloids in cell wall of plants, fungi and outer membrane of Gram Negative bacteria.
