Cyanine3B is one of the brightest fluorophores possessing high sensitivity. Cyanine3B dye maleimide is used to produce maleimide-thiol conjugates via thiols to antibodies, peptides, and other biomolecules with Cyanine3B fluorophore with high fluorescence quantum yield and photostability. Michael-addition of a thiol to a maleimide approach enables the selective method of antibody labeling.
This is a sulfonated dye and can be used for efficient labeling in water buffers.
