Thioflavin-s荧光染色
WebIn this chapter, the application of thioflavin stains to the diagnosis of amyloid is presented. Although Congo red stain is considered the generally accepted standard for the diagnosis of amyloid, this stain requires expertise and the use of polarized light microscopy; moreover, the dye’s diagnostic “apple green birefringence” may be difficult to visualize and therefore … WebMay 24, 2024 · Amyloid deposits are one of the hallmark pathological lesions of Alzheimer’s disease (AD). They can be visualized by thioflavin-S, silver impregnation, Congo red staining, and immunohistochemical reactions. However, that amyloid deposits generate blue autofluorescence (auto-F) has been ignored. Here, we report that visible light-induced …
