Wright's stain is a composite staining agent that primarily targets nucleic acids and proteins through the action of thiazine dyes, including methylene blue, and eosin. This pH-sensitive stain, optimal at pH 6.4-6.7, facilitates the differentiation of cytoplasmic and nuclear morphology by producing contrasting colors; thiazine dyes yield purple staining of nucleic acids, while eosin binds to cytoplasmic proteins to impart a red hue. Wright's stain effectively reveals fine structural details of blood and bone marrow cells, allowing for the rapid assessment of cell morphological abnormalities.
