iFluor® 460 maleimide

AAT Bioquest's iFluor® dyes are optimized for labeling proteins, particularly antibodies. These dyes are bright, photostable, and have minimal quenching on proteins. Although the 460 nm blue diode laser is being installed in numerous new fluorescence instruments, few dyes can be well excited at 460 nm. iFluor® 460 is optimized to be well excited by the blue diode laser at 460 nm, enabling new biological applications for the new fluorescence instruments equipped with the 460 nm blue diode laser. iFluor® 460 maleimide is stable and shows good reactivity and selectivity with the thiol group.

Fluorescent dye maleimides are the most popular tool for conjugating dyes to a peptide, protein, antibody, thiol-modified oligonucleotide or nucleic acid through their SH group. Maleimides react readily with the thiol group of proteins, thiol-modified oligonucleotides, and other thiol-containing molecules under neutral conditions. The resulting dye conjugates are quite stable.
