Cy3 NHS ester is a reactive dye for the labeling of amino-groups in biomolecules. This reagent is ideal for the labeling of soluble proteins, peptides, and oligonucleotides/DNA. For delicate proteins consider using water-soluble sulfo-Cy3 NHS ester which does not require use of any co-solvent.
Cy3 NHS ester can replace NHS esters of Alexa Fluor 546, and DyLight 549.
