General description

Methylene blue is a heterocyclic aromatic chemical, appearing as a dark green solid powder, changing to blue in aqueous solution. It is used as a stain in many different histology procedures, as well as in molecular biology laboratories.

Application

Methylene Blue hydrate is suitable for use as a nucleic acid stain for agarose and polyacrylamide gel electrophoresis (PAGE). It was used to stain 4T1 tumor cells to study metastasis of tumor cells using clonogenic assay. Methylene blue hydrate crystals were encapsulated in apoferritin nanocages for photodynamic therapy against tumor cells.

Features and Benefits

  • Less hazardous than staining with ethidium bromide
  • Viewable in visible light
  • Fast and easy to use
