Chemical Structure
Ruthenium red
Synonym(s): Ammoniated ruthenium oxychloride
- CAS No.: 11103-72-3
- Formula:Cl6H42N14O2Ru3
- Molecular Weight:786.35
SMILES: [NH3][Ru](O[Ru]([NH3])([NH3])([NH3])([NH3])O[Ru]([NH3])([NH3])([NH3])([NH3])[NH3])([NH3])([NH3])([NH3])[NH3].[6+].[Cl-].[6]
Biological Activity: Ruthenium red (Ammoniated ruthenium oxychloride) is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium red strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium red is a L-type calcium current (ICa) blocker. When using Ruthenium Red to stain plant tissue sections affected by pathogens, the breakdown of mucilaginous substances by the pathogens prevents them from taking up the stain, whereas the cell walls of healthy tissue stain red[1][2].
