Aniline blue is used to stain collagen fibers in tissue sections using the Masson′s trichrome protocol for staining multiple components. Collagen is stained blue by this method. It has also been used to stain and visualize glycosylated proteins.
Aniline blue (also known as cotton blue and ink blue) is a component of commonly used polychrome stains. It is used to stain collagen fibers in tissue sections using Masson's trichrome protocol for staining multiple components. Collagen is stained blue by this method. The dye is suitable for selective staining of callose in plant specimens and staining histones for assessing nuclear maturity. Heidenhain's AZAN stain and the Mallory's polychrome stain both entail staining steps using aniline blue-orange G mixtures. Aniline blue is used in Gomori's one-step trichrome stain and Mallory's connective tissue stain for tissue including kidney and intestine.
