Regulation
Purpose It is used to detect elastic fibrin in tissues.
Working Principle Elastic dyes bind to elastin proteins, making elastic fibers appear darker. This helps to highlight the elastic fibers in tissue sections. A mixture of picro acid and acidic fuchsin stains collagen fibers red and other connective tissue components yellow. This different staining allows collagen and elastic fibers to be easily distinguished from each other. This staining method provides important information in textural and pathological examinations by clarifying elastic and collagen fibers. The appearance of elastic fibers in dark purple/black and collagen fibers in red allows these structures to be easily distinguished under light microscopy.
