DESCRIPTION
General description
Methylene blue is used to stain animal cells to make their nuclei more observable. It is a component of staining media such as Wright′s stain and Jenner′s stain.
Methylene blue, also known as methylthioninium chloride, is a photoactive phenothiazine dye.[1] It is a small molecular weight dye,[2] which is effective against Gram positive and Gram negative bacteria.[3]
Application
Methylene Blue solution has been used to stain human amniotic fluid stem cells to determine cell viability.[4] It has also been used to stain sections to determine the presence of mycobacteria.[5][6]
Methylene blue is used to stain blood films/smears used in cytology and to stain RNA or DNA for viewing under the microscope or on hybridization membranes.
