Detecting and imaging RNA molecules in living cells is extremely important for a wide variety of molecular biology procedures including physical transportation, interpretation of genetic information, regulation of gene expression and some essential bio-catalytic roles. The major challenge to stain RNA in living cells is the interferences caused by DNA. In order to address the difficulty, a novel green fluorogenic dye was developed as a RNA-selective probe. AAT Bioquest's Cell Navigator® Live Cell RNA Imaging Kit includes StrandBrite™ RNA Green as it specifically binds RNA in cells. Compared to commercial SYTO™ RNA Select dye for RNA staining in vivo, StrandBrite™ RNA Green shows brighter signal and much better selectivity to RNA. In addition, this kit can stain RNA in both living cells and fixed cells.
