Product Description

CF® Dye amines are reactive molecules for labeling activated carboxylic acid groups in proteins and other biological molecules. Carboxylic acid groups can be activated using water soluble carbodiimides to react with amine-functionalized dyes by forming a stable amide bond.

  • Label activated carboxylic acids in proteins or other biomolecules.
  • Bright, photostable and water-soluble CF® Dyes are excellent options for fluorescent labeling.
  • Available in a range of dye colors, from UV to near-infrared (NIR).

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.
