CF® Dye Succinimidyl Ester
CF® Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues.
Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.
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.
Cyanine NS Dye Succinimidyl Ester
Cyanine NS succinimidyl esters are non-sulfonated cyanine dyes that can be used to label proteins, oligonucleotides and nucleic acids. Available in 3 colors, Cyanine 488NS, Cyanine 555NS, and Cyanine 647NS are designed to match by charge and molecular weight for 2D DIGE platform.
FAM SE, 5 and 6 isomers
5(6)-FAM SE (full name: 5-(and-6)-Carboxyfluorescein, succinimidyl ester mixed isomers) is an amine-reactive green fluorescent dye widely used for labeling proteins or other molecules that contain a primary or secondary aliphatic amine. The coupling reaction is usually carried out at pH 8-9.5.
