Product Description

CF® dyes with a tetrazine group reacts with cyclooctene (TCO, methylcyclopropene) labeled molecules via copper-free click chemistry. Copper-free bioorthogonal reactions are useful for labeling live cells, or when there are concerns about native protein function loss with copper in cell extracts.

  • Fluorescent labeling of cyclooctene (TCO, methylcyclopropene) groups on target molecules via copper-free bioorthonal chemistry.
  • Faster reaction kinetics than methyltetrazine derivatives.
  • Bright, photostable and water-soluble CF® dyes are excellent options for fluorescent labeling.

We also offer CF® dye methyltetrazines and CF® dye TCO.

Superior CF® Dyes

Biotium’s next-generation CF® dyes were designed to be highly water-soluble with advantages in brightness and photostability compared to Alexa Fluor®, DyLight®, and other fluorescent dyes. Learn more about CF® Dyes. For more information download the CF® Dye Brochure.
