Thiazole orange dimer YOYO 1 is a green fluorescent dye utilized for DNA staining. It is a monomethine cyanine dye, presenting as a tetracationic homodimer of oxazole yellow (YO), and is typically supplied as a tetraiodide salt. While exhibiting low fluorescence in aqueous buffer, its intensity significantly increases upon binding to double-stranded DNA through diintercalation.
