CF® Dye Succinimidyl Esters (SE), also known as N-hydroxysuccinimide (NHS) esters are amine-reactive fluorescent dyes. They are commonly used to label primary amines of antibodies and other proteins, amine-modified oligonucleotides and other amine-containing molecules.

Product Description

CF® dye SE or NHS esters are amine-reactive forms of Biotium’s bright and photostable CF® dyes. The SE group on the dye molecule reacts with primary amines such as lysine residues of antibodies or proteins, amine-modified oligonucleotides and other amine-containing molecules to form a stable amide linkage.

• Amine-reactive fluorescent dyes
• Label antibodies, proteins, amine-modified oligonucleotides and other amine-containing molecules
• 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 Alexa Fluor®, DyLight®, and other fluorescent dyes.
