Cyanine3B in Fluorophores

Absorption max 559 nm Emission max 571 nm Fluorophore chart

Cyanine3B is a yellow-emitting cyanine dye that is an improved version of the Cyanine3 fluorophore with significantly higher fluorescence quantum yield and photostability. Due to the fixed conformation, Cyanine3B has the highest emission quantum yield compared to other dyes of this wavelength.

Cyanine3B amine

Amino derivative of Cyanine3B, a reactive dye with significantly increased fluorescence quantum yield and photostability for the conjugation with activated esters and epoxides.
