Methyl Green 0.8% is an aqueous solution of the synthetic basic dye Methyl Green dissolved at a concentration of 0.8%. This particular dye is well known in histology and cytology for its outstanding properties for staining cell nuclei and other cellular structures.

Methyl Green 0.8% binds to the acidic components within cell structures, particularly DNA, and stains these structures green. This bright green allows detailed examination and assessment of cell nuclei as well as other cellular changes and morphological differences in tissue sections. In addition, Methyl Green 0.8% is often used in combination with other dyes, such as pyronine. This combination allows double or multiple staining of different cell structures and tissue components.

Such a technique is known as methyl green-pyronine staining and allows differential visualization of cell nuclei, which are stained green, and RNA, which appears red. Thus, methyl green 0.8%, with its high concentration and ability to bind to acidic components in cell structures, is an indispensable solution for histological and cytological staining applications. Whether used alone or in combination with other dyes, it enables precise and differentiated visualization of cell structures and tissue components.
