Product Description

Streptavidin conjugates are high quality streptavidin biotin binding protein labeled with CF® dyes and a selection of other labels. CF® dyes are Biotium’s signature fluorescent dyes with exceptional brightness and photostability. See the CF® Dye Brochure for more information.

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