Mallory staining method
The Mallory staining method makes use of three different dyes. This method has the advantage of visualizing a larger number of tissue structures. Mallory stain combines aniline blue, which stains connective tissue, extracellular matrix, glycoproteins, and mucus, orange G, which stains proteins, and the dark red fuchsin, which stains RNA and DNA.
