Product Description

CF® dyes conjugates of Streptavidin are high quality biotin-binding proteins labeled with the superior CF® dyes or a selection of other labels. These conjugates are typically used as secondary reagents to detect biotinylated probes such as primary antibodies for flow cytometry, western blotting, immunofluorescence staining, and other applications.

  • Conjugates with wide choice of CF® dye colors, plus HRP, R-PE, APC, and Alkaline Phosphatase
  • Superior CF® dyes are bright, photostable, and water-soluble
  • Ideal for flow cytometry, western blotting, and immunofluorescence staining

Blue dyes have lower fluorescence and can give higher non-specific background than other dye colors. Conjugates of blue fluorescent dyes like CF®350, CF®405S, and CF®405M are not recommended for detecting low abundance targets.

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.
