Description
Fuchsin acid M.S., also known as acid fuchsin, is a synthetic dye belonging to the family of triarylmethane dyes. It is commonly used as a histological stain in microscopy and as a dye in various laboratory procedures. Fuchsin acid M.S. is particularly valued for its affinity to acidophilic structures, staining tissues such as collagen and cytoplasmic components in shades of red.
In histology, acid fuchsin is used as a component of staining solutions such as Mallory’s triple stain and Masson’s trichrome stain, where it stains muscle fibers and connective tissues. It is also utilized in other staining techniques for biological specimens, including blood smears and bacterial samples.
The “M.S.” designation typically refers to the dye content, indicating that the product has been standardized to a specific concentration or purity level for consistent laboratory use.
