Chemical compound
The inorganic dyeammoniatedruthenium oxychloride , also known asruthenium red , is used inhistology tostain aldehyde fixed mucopolysaccharides .
Ruthenium red (RR) has also been used as a pharmacological tool to study specific cellular mechanisms. Selectivity is a significant issue in such studies as RR is known to interact with many proteins.[ 1] These include mammalian ion channels (CatSper1 ,TASK ,RyR1 ,RyR2 ,RyR3 ,TRPM6 ,TRPM8 ,TRPV1 ,TRPV2 ,TRPV3 ,TRPV4 ,TRPV5 ,TRPV6 ,TRPA1 ,mCa1 ,mCa2 ,CALHM1 [ 2] [ 3] )TRPP3 ,[ 4] a plant ion channel,Ca2+ -ATPase ,mitochondrial Ca2+ uniporter ,[ 5] tubulin ,myosin light-chain phosphatase , and Ca2+ binding proteins such ascalmodulin . Ruthenium red displays nanomolar potency against several of its binding partners (e.g. TRPV4,ryanodine receptors,...). For example, it is a potent inhibitor of intracellularcalcium release by ryanodine receptors (Kd ~20 nM).[ 6] As a TRPA1 blocker, it assists in reducing the airway inflammation caused bypepper spray .
RR has been used on plant material since 1890 for stainingpectins ,mucilages , andgums . RR is a stereoselective stain for pectic acid, insofar as the staining site occurs between each monomer unit and the next adjacent neighbor.[ 7]
