Introduction
Histology, cytology and other related scientific disciplines study the microscopic anatomy of tissues and cells. In order to demonstrate a good tissue and cellular structure, the samples need to be stained in a correct manner. Azure II Eosinate powder dye is used in various staining methods in microscopy. It is created by mixing equal ratios of Azure B, Methylene Blue and Eosin Y powder dyes. It is a component of Giemsa stain and is also used for preparing Romanowsky-Giemsa stain.
