R-C-3721	SY-7 NHS ester	SY-7 NHS Ester is a nonfluorescent acceptor dye for preparation of peptide and oligonucleotide FRET probes.The NHS ester(or succinimidyl ester)is the most popular amine reactive group for labeling with the primary amines of proteins (Lys),amine-modified oligonucleotides,and other amine-containing molecules.The labeling occurs most efficiently at pH 7-9 and forms a stable, covalent amide bond.	price>
R-C-3722	SY-9 NHS ester	SY-9 is a more hydrophilic version of the popular SY-7 dark quencher .This nonfluorescent acceptor dye is often used for the preparation of peptide FRET probes.The NHS ester(or succinimidyl ester)is the most popular amine reactive group for labeling with the primary amines of proteins(Lys),amine-modified oligonucleotides, and other amine-containing molecules.The labeling occurs most efficiently at pH 7-9 and forms a stable,covalent amide bond.	price>
R-C-3723	SY-21 NHS ester	SY-21NHS Ester (QSY®-21 succinimidyl ester equivalent) is a nonfluorescent acceptor dye often used for preparation of peptide and oligonucleotide FRET probes. A broad and intense quenching range from 580 nm to 680 nm makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with fluorescent dyes at 580 nm to 680 nm, such as Fluorescein,Alexa Fluor® 568, 594, 633, 647, TAMRA, ROX, Texas Red and Cy5.	price>
