Histological staining originally designed for staining the malarial parasite, but also useful as a histological stain for cytology, blood cells and bone marrow smears.
The dark staining has a predilection for the phosphate groups within DNA and therefore stains DNA-rich regions such as the chromatin and the nuclear membrane. Within the chromosomes, certain regions are richer in adenine and thymine giving rise to appearence of banding, known as G-banding.
