There provided, inter alia, reagents and methods for modulation fluorescence of a tetrazine containing compound and/or a dienophile-containing compound. There is provided a method of detecting binding of a first affinity ligand and a second affinity ligand, the method includes the follow steps. Contacting a tetrazine-containing compound with a dienophile-containing compound, the tetrazine-containing compound comprising a first affinity ligand covalently attached to a tetrazine moiety and the dienophile-containing comprising a second affinity ligand covalently attached to a dienophile moiety. |
