NHS Ester Dyes

Amine-reactive fluorescent dyes are widely used to modify amino acids, peptides, proteins (in particular, antibodies), oligonucleotides, nucleic acids, carbohydrates and other biological molecules.  NHS esters (ie, succinimidyl esters) are proven to be the best reagents for amine modifications because the amide bonds formed are as stable as the natural peptide bonds, and the resulting fluorescent biocojugates are generally more stable than  fluorescent conjugates using  FITC (fluorescein isothiocyanate).  NHS esters  react with primary amines in physiologic to slightly alkaline conditions (pH 7.2 to 9) to yield stable amide bonds, and releases N-hydroxysuccinimide (NHS).
