BP Fluor 660 (almost identical to Alexa Fluor® 660 and CF660® 680RD) Maleimide is a bright and photostable far-red dye that emits fluorescence at about 685 nm in the borderline spectral region between far-red and near-IR. Although the absorption maximum is at around 665 nm, this dye can be sufficiently excited by the 633 or 647 nm laser. It reacts with the thiol- or cysteine group in antibody, proteins, peptides, SH-modified oligos, and other target molecules. Reagent grade, for research purpose.
