What does methylene blue stain? 

Methylene blue can be used to stain or highlight parts of animal, bacteria, and blood tissue specimens. Methylene blue stains acidic cell parts (like the nucleus) blue; it's a good counter-stain with Eosin Y. 

Use methylene blue to make a smear of cheek cells, or as an optional material in this mold observation science project! You can also check out our Microscope Slide Stains article to learn more about various stains.
