iFluor(TM) 405 maleimide

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) 405 dyes have fluorescence excitation and emission maxima of ~400 nm and ~420 nm respectively. These spectral characteristics make them an excellent alternative to Alexa Fluor® 405 labeling dye (Alexa Fluor® is the trademark of Invitrogen). iFluor(TM) 405 maleimide is stable and shows good reactivity and selectivity with thiol group.
