iFluor(TM) 532 succinimidyl ester

AAT Bioquest's iFluor(TM) dyes are optimized for labeling proteins, in particular, antibodies. These dyes 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(TM) 532 dyes have fluorescence excitation and emission maxima of 540 nm and 560 nm respectively. These spectral characteristics make them an excellent alternative to Alexa Fluor(R) 532 labeling dye (Alexa Fluor(R) is the trademark of Invitrogen). iFluor(TM) 532 SE is reasonably stable and shows good reactivity and selectivity with protein amino groups.
