Biebrich Scarlet Acid Fuchsin is an important histological stain used to differentiate various tissue components, particularly in connective tissue studies. This staining method is a combination of two dyes: Biebrich Scarlet and Acid Fuchsin. Together, they are often used in staining protocols such as the Masson's Trichrome stain, which helps to visualize collagen and muscle fibers.
