Product Description

CF® Dye alkynes can react with azide groups to form 1,2,3-triazole via 1,3-dipolar Huisgen copper-catalyzed cycloaddition. They can also be used as monomeric building blocks to copolymerize with other monomers to form fluorescent polymers.

  • Fluorescent detection or labeling azide groups on target molecules.
  • Can be used as fluorescent monomers to form dye-labeled polymers.
  • 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.

    CF® Dye Azide

    CF® Dyes with an azide group. Can be used to label or detect alkyne, BCN or cyclooctyne-containing molecules by fluorescence spectroscopy, microscopy or flow cytometry following copper-catalyzed azide-alkyne cycloaddition.

    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.

    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.
