Methylene blue (1% aqueous solution)

Methylene Blue is a popular alkaline stain used to stain animal cells to make nuclei more visible. Methylene blue binds DNA which is very abundant in the nucleus. Cell stained by methylene blue will show the nucleus with deep blue color. It also helps make cells show up against their background, where their shape can help you determine what they are (their morphology). Methylene blue is also used by aquarium hobbyist for preventing fungal disease.



Eosin Y (0.5% aqueous solution)

Eosin Y Stain is a counterstain to Methylene Blue. It is most commonly used as an acidic red stain for highlighting red blood cells, cytoplasmic material, cell membranes, and extracellular structures in pink or red colors. In the hospital, Eosin's most important medical uses are H&E (haematoxylin and eosin) staining. H&E staining is one of the most commonly used techniques in histology. Tissue stained with haematoxylin and eosin shows cytoplasm stained pink-orange and nuclei stained darkly, either blue or purple.
