iFluor® 750 hydrazide
AAT Bioquest's iFluor® dyes are developed for labeling proteins, particularly antibodies. These dyes are optimized to have minimal fluorescence quenching effect on proteins and nucleic acids. Our iFluor® 750 dyes have fluorescence excitation and emission maxima of ~757 nm and ~779 nm, respectively, with good photostability. Our in-house comparable studies indicated that our iFluor® 750 dyes are significantly brighter than the corresponding Cy7® and Alexa Fluor® 750. These spectral characteristics make them a superior alternative to Cy7® and Alexa Fluor® 750 (Cy7® and Alexa Fluor® are the trademarks of GE Healthcare and Invitrogen). iFluor® 780 conjugates have been widely used in fluorescence animal imaging applications. The iFluor® 750 hydrazide is reasonably stable and shows good reactivity and selectivity with the carbonyl group (such as aldehyde).
