CF® Dye SE/TFP Esters are amine-reactive forms of Biotium’s bright and photostable CF® Dyes. The succinimidyl ester (SE) group, also known as N-hydroxysuccinimide (NHS) esters, on the dye molecule reacts with primary amines such as lysine residues of antibodies or proteins, amine-modified oligonucleotides and other amine-containing molecules to form a stable amide linkage. CF® Dye TFP (tetrafluorophenyl) esters are more stable alternatives to succinimidyl ester. CF® Dye TFP esters are available for CF®850 and CF®870, Biotium’s industry-leading near-infrared dyes with emission above 850 nm.

• Amine-reactive fluorescent dyes with high labeling efficiency
• Label antibodies, proteins, amine-modified oligonucleotides and other amine-containing molecules.
• Offered with Biotium’s bright and photostable CF® Dyes which provide superior signal-to-noise
• Available in 35 CF® Dye colors from blue to near-IR wavelengths
• Near-IR CF®850 and CF®870 TFP esters offer emission above 850 nm

Due to Biotium’s unique manufacturing and packaging process, our amine-reactive CF® Dyes are provided with the highest purity and more stable ester dye forms than other vendors. As a result, our CF® Dye SE/TFP products retain more reactivity and provide a higher labeling efficiency for users.

Superior CF® Dyes

CF® Dyes are Biotium’s line of next-generation fluorescent dyes that have improved brightness, photostability, and water solubility compared to Alexa Fluor®, DyLight®, and other fluorescent dyes. Learn more about CF® Dyes. For more information download the CF® Dye Brochure.
