Product Description

CF® Dye Succinimidyl Esters (SE), also known as N-hydroxysuccinimide (NHS) esters are amine-reactive forms of Biotium’s bright and photostable CF® dyes. The SE group 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.

  • 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 33 CF® Dye colors from blue to near-IR wavelengths

Due to Biotium’s unique manufacturing and packaging process, our amine-reactive CF® dyes are provided with the highest purity and more stable SE dye forms than other vendors. As a result, our CF® Dye SE 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.
