    Carboxyrhodamine 110-C5-Maleimide, 5 and 6 isomers

    From: $331 Sizes: 5 mgCatalog #: 91029

    CR110-C5-maleimide (full name: 5(6)-Carboxyrhodamine 110-C5-maleimide) is a maleimide derivative of the green fluorescent dye carboxyrhodamine 110. The dye has spectral properties (λ Ex/λ Em (MeOH) = 502/524 nm) similar to those of fluorescein (fluorescein-5-maleimide, for example), but the photostability of the dye is among the best of all green fluorescent dyes.
