Descriptions	Thiazole orange dimer YOYO 1 Thiazole orange dimer YOYO 1 MedChemExpress (MCE) HY-D0916 143413-85-8 YOYO 1 Descriptions Thiazole orange dimer YOYO 1 Thiazole orange dimer YOYO 1 MedChemExpress (MCE) HY-D0916 143413-85-8 YOYO 1 YOYO1 97.00% Solution, -20°C, protect from light, 2 years Room temperature in continental US may vary elsewhere. Thiazole orange dimer YOYO 1 is a green fluorescent dye used for DNA staining. It belongs to the monomethine cyanine dye family and is a tetracationic homodimer of oxazole yellow (abbreviated as YO, hence the name YOYO), usually provided as a tetraiodide salt. In aqueous buffer, the free YOYO-1 dye (λmax 458 nm λmax 564 nm) has a very low fluorescence quantum yield, but after binding to double-stranded DNA through diintercalation, the fluorescence intensity is increased by 3200 times (λmax 489 nm λmax 509 nm). \| \| \| \| \| \| \| \| \| \| [1]. Wang L, et al.Ultrafast Transient Absorption Spectra of Photoexcited YOYO-1 molecules call for additional investigations of their fluorescence quenching mechanism.
