Eosin

Eosin is an acidic dye commonly used to complement hematoxylin in the popular H&E (hematoxylin and eosin) staining protocol, which differentiates cellular and tissue structures in histological analysis. It stains cytoplasmic components, extracellular structures, and connective tissues with a pink to red color. The more common Eosin Y produces brighter and more vibrant pink shades, which are generally preferred for routine H&E staining to enhance contrast with hematoxylin-stained nuclei. Eosin B produces a duller, bluish-pink color, which may be preferred in more specialized situations.
