CF® initially was an abbreviation for Cyanine-based Fluorescent dyes. These were the first patented CF® Dyes based on cyanine dye structures. Since then, our CF® Dye patent portfolio has expanded to include four different fluorescent dye core structures that cover the fluorescence spectrum from UV to NIR. Today, we believe “CF” more aptly stands for Clear Fluor: dyes that produce superior signal-to-noise.
