Jenner's Stain (methylene blue eosinate) is used in microscopy for staining blood smears. The stain is dark blue and results in very observable clearly stained nuclei.Romanowsky stain solutions are used in hematology. They are composed of methylene blue, oxidative products of methylene blue (Azure A, Azure B, Azure C, and Thionin) and eosin dyes. Giemsa, a commonly used stain, does not adequately stain red blood cells, platelets, or white blood cell cytoplasms when used alone.
