BP Fluor 660R 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 635 nm laser.
BP Fluor 660R provides Alexa Fluor 660R-comparable brightness and performance at a significantly lower cost. With low background, strong photostability, and excellent spectral compatibility, they deliver reliable fluorescence results while helping maximize research budgets.
