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.
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.
FITC (Isomer I)
FITC (fluorescein-5-isothiocyanate) is an amine-reactive fluorescein derivative for labeling proteins or other molecules containing primary amines.
