iFluor™ 350 dyes have fluorescence excitation and emission maxima of ~350 nm and ~440 nm respectively. These spectral characteristics make them an excellent replacement for AMCA and Alexa Fluor® 350 labelling dye (Alexa Fluor® is the trademark of Invitrogen). ReadiLink™ labelling kits essentially only require 2 simple mixing steps without a column purification needed. iFluor™ 350 SE used in this ReadiLink™ kit is reasonably stable and shows good reactivity and selectivity with protein amino groups. The kit has all the essential components for labelling ~2×50 ug antibody. Each of the two vials of iFluor™ 350 dye provided in the kit is Optimised for labelling ~50 µg antibody. iFluor™ 350 SE protein labelling kit provides a convenient method to label monoclonal, polyclonal antibodies or other proteins (>10 kDa) with the iFluor™ 350 SE.

ReadiLink™ iFluor™ 488 Antibody Labelling Kit *Microscale Optimised for Labelling 50 µg Antibody Per Reaction*

Although FITC is still the most popular fluorescent labelling dye for preparing green fluorescent bioconjugates, there are certain limitations with FITC, such as severe photobleaching for microscope imaging and pH-sensitive fluorescence. Protein conjugates prepared with iFluor™ 488 dyes (Ex/Em=497 nm/525 nm) are far superior compared to conjugates of fluorescein derivatives such as FITC. iFluor™ 488 conjugates are significantly brighter than fluorescein conjugates and are much more photostable. Additionally, the fluorescence of iFluor™ 488 is not affected by pH (4-10). This pH insensitivity is a major improvement over fluorescein, which emits its maximum fluorescence only at pH above 9. ReadiLink™ labelling kits essentially only require 2 simple mixing steps without a column purification needed. iFluor™ 488 SE used in this ReadiLink™ kit is reasonably stable and shows good reactivity and selectivity with protein amino groups. The kit has all the essential components for labelling ~2×50 ug antibody. Each of the two vials of iFluor™ 488 dye provided in the kit is Optimised for labelling ~50 µg antibody. iFluor™ 488 SE protein labelling kit provides a convenient method to label monoclonal, polyclonal antibodies or other proteins (>10 kDa) with the iFluor™ 488 SE.
