Rose bengal

CAS: 632-68-8

Rose bengal is a fluorescent dye that is used in biochemical research as a cell-labeling agent. It can be used to label cells for microscopy, flow cytometry, and other techniques. Rose bengal binds to DNA and RNA and can activate ion channels in the plasma membrane, which leads to depolarization of the membrane potential. This chemical has been shown to inhibit ligand-dependent activation of G protein-coupled receptors by binding to the receptor's extracellular domain. Rose bengal has also been shown to be an effective inhibitor of phospholipase A2 activity.
