| Application: | Methylene Blue hydrate has been used: • in the preparation of methylene blue (MB) solution to stain zymograms • to label the injection site in the tissue slices • to pre-treat mice via oral gavage to study its effects on noise-induced hearing loss |
| Biochem/physiol Actions: | Methylene blue (MB) plays a key role in microbiology and pharmacology. It is mainly used in staining live organisms and in methemoglobinemia treatment. MB can be considered as a possible and safe vasoconstrictor. It has several applications in textile, paper and hair coloring sectors. |
| General description: | Methylene Blue (MB) is a basic histological dye. |
