CFQ520 succinimidyl ester
The amine-reactive quencher, CFQ520 succinimidyl ester, has a broad and intense absorption (approximately 520 nm) but no fluorescence, making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications.

CF® Dye Succinimidyl Ester
CF® dye SE or 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.
Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.

Carboxyrhodamine 110-X succinimidyl ester, 5 and 6 isomers
5-(and-6)-Carboxyrhodamine 110-X, succinimidyl ester (5(6)-CR 110-X, SE) readily couples to a primary or secondary amine. The dye is a superior alternative to 5(6)-SFX because of its exceptional phototostability and fluorescence insensitivity to pH (4-9).
