What is the purpose of Romanowsky staining?
In the context of microscopy, staining is considered as an essential step during enhancement of the contrast of the microscopic image, especially to highlight different structures in biological tissues. During the staining of peripheral blood and bone marrow smears, Wright and Giemsa stains are used. These stains are known as Romanowsky stains. Both these stains are composed of important components: oxidized methylene blue, eosin Y, and azure B dyes. The function of methylene blue and azure B is to stain the nucleus with colors varying from blue to purple. These stains are widely used during the study of red blood cell morphology and during the performance of differential white blood cell counts. Diagnosis of different disease conditions such as leukemia could be achieved through Romanowsky staining procedures. Wright staining is used to differentiate blood cells which consist of a mixture of eosin and methylene blue dyes.
