A high quality biotin-binding protein conjugated to Biotium's signature bright and photostable fluorescent CF® dyes, and a selection of other labels.

• Conjugates with wide choice of CF® dyes colours, 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

CF® dyes conjugates of streptavidin are high quality biotin-binding proteins labelled 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.

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

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.
