Description and Uses

Methylene Blue trihydrate finds many uses in biology and chemistry. It acts as a GCS inhibitor, biological stain and redox indicator. It inhibits tau filament formation. Further, it is reported to bind to the M2 subtype of muscarinic receptors in rat cardiac myocytes and thus exhibit antimuscarinic effects on IK, ACh and ICa. It also inhibits endothelium-dependent relaxation of isolated blood vessels.
