Product Description

This kit contains reagents for labeling antibodies or other proteins with a fluorescent CF® dye succinimidyl ester (CF® dye SE) or biotin succinimidyl ester (biotin SE). Learn more about next-generation CF® dyes with superior brightness, photostability, and water solubility compared to other fluorescent dyes.


  • 3 labeling reactions of 1 mg each
  • Choice of biotin or CF® dyes ranging from UV to near-IR
  • Includes buffers & ultrafiltration vials for labeling & purification

Kit Components

  • Lyophilized CF® Dye SE or Biotin SE (3 vials)
  • Anhydrous DMSO
  • Sodium Bicarbonate Solution, pH 8.3
  • 1X PBS, pH 7.4
  • Ultrafiltration Vials, 10K MWCO (3 vials)
  • Reaction Vials (3 vials)
  • Storage Vials (3 vials)
Note: Conjugates of blue-fluorescent dyes like CF®350, CF®405S and CF®405M are not recommended for detecting low abundance targets and may be challenging to use in tissue specimens. Blue dyes have lower fluorescence and photostability, and cells and tissue have high autofluorescence in blue wavelengths, resulting in lower signal to noise compared to other colors.
