Cell Navigator? Live Cell RNA Imaging Kit *Green Fluorescence*. 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.
