Giemsa stain is a versatile differential stain that is widely used in hematology for blood and bone marrow specimens, clinical cytology specimens, bacteriology, histological biopsies, and tumor samples. Giemsa's staining solution is composed of methylene blue, azure, and eosin. It is a major histological stain due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. The stain is frequently used in combination with other dye solutions: May-Grünwald’s solution for Pappenheim (MGG) and Wright-Giemsa.

Acridine is a small cationic and planar dye that mainly binds to RNA and DNA. These dyes are strongly fluorescent. It resembles the structure of xanthene except that the heteroatom is nitrogen, not oxygen. Acridine is suitable for nucleic acid staining, particularly for cell cycle determination. Acridines are used as fluorescent materials for visualisation of biomolecules, and in laser technologies.
