methylene blue

[meth´ĭ-lēn]

a synthetic organic compound, in dark green crystals or lustrous crystalline powder, used in treatment of methemoglobinemia, as a stain in pathology and bacteriology, and as a diagnostic aid in the detection of the premature rupture of fetal membranes.

meth·y·lene blue

(meth'ĭ-lēn blū), [C.I. 52015]

A basic dye easily oxidized to azure with dye mixtures; used in histology and microbiology to stain intestinal protozoa in wet mount preparations, to track RNA and RNase in electrophoresis, and as an antidote for methemoglobinemia; its redox indicator properties are useful in milk bacteriology.
