Beschreibung: Wright′s Stain solution is commercially available and is generally used in hematology. Its preparation involves heating methylene blue with sodium bicarbonate and combining the mixture with eosin. It is alkaline, hence, its concentration is continuously changing due to the progressive oxidizing action of the alkali. Therefore, Giemsa′s stain is added to preserve the azurophilic properties of polychrome dyes.

Beschreibung: When blood films are stained using Wright-Giemsa Stain, the white blood cell nucleus and cytoplasm take on the characteristic blue or pink coloration. The combination of purified eosin and thiazine dyes in the product eliminates inconsistent staining and yields reproducible chromogenic responses.

Beschreibung: Sudan Red 7B has been used to stain the fat bodies of Ostrinia nubilalis (Hübner) larvae. Sudan red 7B, also known as fat red, is a non-fluorescent stain.[2] It is effectively used to stain lipids and is used to indicate the presence of suberin in cell walls.[2][3][4] Sudan red 7B acts as a marker for formosan subterranean termite, Coptotermes fornosanus Shiraki.
