Cy3 NHS ester is a reactive cyanine dye containing NHS group which enables labeling of amino-bearing biomolecules. This reagent is ideal for the labeling of soluble proteins, peptides, and oligonucleotides/DNA. Cyanine3 NHS ester is an analog of Cy3? NHS ester and can replace Alexa Fluor 546 as well as DyLight 549.
