Product Description

CF® dye azide can react with terminal alkynes to form 1,2,3-triazole via copper-catalyzed cycloaddition. They can also undergo Staudinger ligation with a phosphine containing compounds. The azide derivatives also react with cyclooctynes and BCN groups via copper-free bioorthogonal reaction.

  • Fluorescent detection or labeling of alkyne, BCN or cyclooctyne groups on target molecules.
  • Bright, photostable and water-soluble CF® dyes are excellent options for fluorescent labeling.

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.

We also offer CF® dye Picolyl Azide derivatives for azide-alkyne cycloaddition reactions at lower copper concentrations, suitable for labeling live cells or other copper-sensitive systems.

    CF® Dye BCN

    CF® Dyes with a BCN group react with azides via a copper-free bioorthogonal reaction to label target molecules for surface staining of live cells or cell extracts. Membrane-permeant CF® Dye BCN conjugates for intracellular labeling reactions are also available.

    DMSO, Anhydrous

    Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.

    CF® Dye SE/TFP Ester

    CF® Dye SE/TFP esters are amine-reactive fluorescent dyes. They are commonly used to label primary amines of antibodies and other proteins, amine-modified oligonucleotides and other amine-containing molecules.

    CF® Dye Picolyl Azide

    CF® dye picolyl azide derivatives fluorescently label alkyne groups on biomolecules via the standard azide-alkyne cycloaddition, but at low copper concentrations.

    Biotin BCN

    Biotin BCN, an alternative to biotin labeled DIBO and DBCO, reacts with azide to form 1,2,3-triazole by copper free 1,3-dipolar Huisgen cycloaddition.

    CF® Dye Alkyne

    CF® Dye alkynes react with azide groups via copper-catalyzed bioorthogonal cycloaddition. Can be used to fluorescently detect or label azide groups on target molecules. CF® Dye alkynes can also be used as building blocks to form fluorescent polymers.
