Product Description

CF® dye aminooxy (aka hydroxylamine or aminooxyacetamide) derivatives are reactive molecules that readily react with aldehyde or ketone groups to form a stable oxime linkage without the use of reducing agents.

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.

  • Stable labeling of aldehyde or ketone groups on polysaccharides, glycoproteins or antibodies.
  • Bright, photostable and water-soluble CF® dyes, excellent options for fluorescent labeling.
  • Available in a range of dye colors, from UV to near-infrared (NIR).

We also offer CF®DI Aminooxy, which are designed to match each other for dye molecular weight and charge, and do not alter the pI of labeled proteins.
