Buy Methylene Blue

Buy Methylene Blue – Methylene blue (methylthioninium chloride) is a synthetic, redox-active dye from the phenothiazine class. The planar, cationic molecule is deep blue when oxidised and converts on reduction into the colourless leuco form, forming a reversible redox pair with a low redox potential. In basic research it serves as a model substance for electron transfer processes: studies examine its action in isolated mitochondria as an alternative electron carrier between respiratory chain complexes, its use as an electron acceptor for NADH-dependent oxidoreductases in cell-free systems, and its generation of reactive oxygen species as a photosensitiser under illumination. It is also described as a classical histological stain and a reference analyte in adsorption and catalysis research. For laboratory practice, methylene blue is readily water-soluble, shows a pronounced absorption maximum near 665 nm and tends to dimerise in concentrated solutions, shifting the band; it also stains skin, surfaces and plastics intensely. At Peptélia it is available as a solid in a vial, with solution preparation and storage details on the product page, classified within Skin & Cell Research. Each batch is tested in-house by HPLC and UV/Vis spectroscopy, and the batch certificate of analysis is viewable before purchase. For research use only. Not for use in or on the human body.
