| | TOTO 1 Usage And Synthesis |
| Description | TODi-1 (Thiazole Orange Homodimer, also known as TOTO®-1) is a green fluorescent carbocyanine dimeric dye. TODi-1 is a cell-impermeant nucleic acid stain that is nonfluorescent in the absence of nucleic acids but exhibits a multiple fluorescence enhancement upon binding to dsDNA.
The bright fluorescence signal and low background make TODi-1 ideal for staining nucleic acids on microarrays, as well as for nuclear and chromosome counterstaining in multicolor fluorescence labeling experiments. TODi-1 is non-cytotoxic and may be used for long-term monitoring of cell viability and dead cell detection in culture. | | Chemical Properties | ex/em: 514/533 nm
Extinction coefficient (ε): 117000 cm??1M??1
Quantum yield (Φ): 0.34 | | Definition | ChEBI: ToTo-1 is an organic iodide salt and a cyanine dye. It has a role as a fluorochrome. It contains a ToTo-1(4+). | | Abs/Em Maxima | 514/532 nm |
