CruzFluor™ 350 succinimidyl ester dye is a stable fluorescent marker with selectivity for protein amino groups. CruzFluor™ 350 dye shows good reactivity and has an are excitation of ~350 nm with an emission maxima of ~440 nm. The CruzFluor™ 350 dye are a comparable alternative to AMCA, DyLight® 250 Alexa Fluor® 350 labeling dyes.
The CruzFluor™ family of products are a fluorescent labeling dye series that spans the full visible spectrum, and are useful to conjugate to nucleic acids, proteins and antibodies. The CruzFluor™ dyes are strong reagents for amine modification because they are incorporated with succinimidyl esters, which have a very strong ability to develop amide bonds that are as stable if not identical to the bonds found on a natural peptide.
