iFluor® 350 succinimidyl ester

AAT Bioquest's iFluor® dyes are optimized for labeling proteins, in particular, antibodies. They are bright, photostable and have minimal quenching on proteins. They can be well excited by the major laser lines of fluorescence instruments (e.g., 350, 405, 488, 555 and 633 nm). iFluor® 350 dyes have fluorescence excitation and emission maxima of ~345nm and ~450 nm respectively. These spectral characteristics make them an excellent alternative to AMCA and Alexa Fluor® 350 labeling dye (Alexa Fluor® is the trademark of Invitrogen). iFluor® 350 SE is reasonably stable and shows good reactivity and selectivity with protein amino groups.
