APDye Fluor 647 Maleimide
This product is a far-red fluorescent probe containing a sulfonated 647 dye and a maleimide group. The dye emits bright, photostable fluorescence around 665 nm, while the maleimide reacts selectively with thiols to form stable thioether bonds. Its water-soluble design specifically ensures efficient conjugation for protein labeling, imaging, and bioorthogonal studies.
