CF® Dye Maleimides are thiol-reactive fluorescent dyes. Maleimides are commonly used to label proteins or small ligands like peptides or oligonucleotide thiophosphates on free thiol groups.
- Thiol-reactive fluorescent dyes.
- Stably label antibodies, proteins, or small ligands like peptides or oligonucleotide thiophosphates on free thiol groups.
- 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 other commercially available fluorescent dyes.
