	Romanowsky stain
		Romanowsky staining was a prototypical staining technique that was the forerunner of several distinct but similar methods, including Giemsa[?], Wright[?], and Leishman[?] stains, which are used to differentiate cells in pathologic specimens.
		Ehrlich had used mixtures of acidic and basic dyes for this purpose in 1879: in 1891 Romanowksy[?] and Malakowsky[?] independently developed a technique using a mixture of Eosin Y and oxidated Methylene Blue that was also useful for this purpose.
		Because the aqueous dye solutions were unstable, methanol was introduced as a solvent, and Leishman (in 1901) and Wright[?] (in 1902) advocated use of methanol as a fixative prior to staining.

		The improved staining solution of claim 2 wherein the ratio of Eosin Y to Azure B is from 2.05:1 to 1.66:1 on a dry weight basis.
		Although Methylene Blue is not an essential component for staining, it is very similar in structure to Azure B and is considered to be a contributing factor in formation of the 1:2 ion pair of Eosin Y:blue component.

		The rationale for this stain for glycogen is unknown.
		The stain fades in time and is therefore not used as frequently as the Mallory connective tissue stain.
		The stain is composed of methylene blue eosinate, azure A eosinate, azure B eosinate, and methylene blue chloride; used for differential staining of blood smears, spleen, and bone marrow cells, for staining protozoan parasites such as Plasmodium spp.

	ROMANOWSKY TECHNIQUES © Woods and Ellis 2000
		The 'red' staining of the nuclei of parasitic protozoa is thought to be produced by the azure dye and eosin binding to the basic protein protamine, rather than the nuclear chromatin, to produce an imino base of the azure dye (which is red).
		Numerous modifications of the Romanowsky method have been described, particularly for application to tissue sections and, although the various techniques may produce slight differences in staining, the basic mechanisms and staining effects are the same.
		Stock stains should be stored in tightly capped polyethylene containers, in the dark at 4°C to prolong shelf life, as they are affected by moisture, contact with metals, exposure to light and variation in temperature.

	Wright's stain - Wikipedia, the free encyclopedia
		Wright's stain is also used in cytogenetics to stain chromosomes on slides for visualization and diagnosis of sydromes and disease.
		It is named for James Homer Wright, who devised the stain, a modification of the Romanowsky stain, in 1902.
		There are related stains known as the buffered Wright stain, the Wright-Giemsa stain, and the buffered Wright-Giemsa stain, and specific instructions depend on the solutions being used, which may include Eosin Y, Azure B, and Methylene Blue (some commercial preparations combine solutions to simplify staining).

		In 1900 Leishman was appointed Assistant Professor of Pathology at the Army Medical School and evolved the modification of Romanowsky's stain known as Leishman's stain.
		He used this to stain the elusive parasites which, at the suggestion of Ronald Ross, became known as Leishmania donovani (Leishman and Charles Donovan discovered the protozoon parasites independently and published their findings within a few weeks of each other).
		The stain is also used to this day to stain the protozoon parasites responsible for malaria.
