Congo Sequential Method
It is used for the detection of amyloid on formalin-fixed, paraffin-embedded tissue sections with amyloidosis, and may be used for frozen sections as well. Response surface methodology was investigated to determine the operational parameters on the degradation of Congo red dye (CR) and chemical oxygen demand (COD) in two electrochemical systems evaluated individually on effluent pretreated by an up-flow anaerobic sludge blanket (UASB) reactor. Congo Red staining solution is a specialized histological reagent designed to selectively identify amyloid deposits in tissue sections. Amyloid is an extracellular, eosinophilic, proteinaceous material composed mainly of β-pleated sheet structures, which under electron microscopy appear as.
