General description
BioTracker<TMSYMBOL></TMSYMBOL> Si-DMA Singlet Oxygen Live Cell Dye is a novel far-red fluorescence probe that is composed of silicon-containing rhodamine and anthracene moieties as a chromophore and a singlet oxygen reactive site, respectively. In the presence of singlet oxygen, fluorescence of BioTracker Si-DMA live cell dye increases 17 times due to endoperoxide formation at the anthracene moiety. The dye is highly selective to singlet oxygen, among seven different reactive oxygen species (1O2, O2-, H2O2, HOCL-, RCO-, OH-, NO). Among three different intracellular photosensitizers, BioTracker Si-DMA selectively detects the 1O2 that is generated by 5-aminolevulinic acid-derived protoporphyrin IX, localized in mitochondria. On the other hand, mitochondria-targeted KillerRed and lysosomal porphyrins could not induce fluorescence change in the dye.
