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.
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.
Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.
Cyanine Dye Succinimidyl Ester
Biotium offers high quality amine-reactive succinimidyl ester (SE) dyes used to label proteins, oligonucleotides, and nucleic acids. We offer Cyanine 555 (Cy®3), Cyanine 647 (Cy®5), Cyanine 680 (Cy®5.5), and Cyanine 750 (Cy®7) as high quality succinimidyl esters.
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.
EDC (or EDAC) (1-(3-Dimethylaminopropyl-3-ethylcarbodiimide, hydrochloride)) has recently been found to be very useful for fixing in situ chelators, including the fluorescent ion indicators for histological studies following physiological experiments. EDC is also a widely used reagent to activate carboxy groups for amine coupling.
