Description du produit
Cyanine 3 NHS ester is a reactive dye for the labeling of amino-groups in biomolecules, an analog of Cy3® NHS ester. This reagent is ideal for the labeling of soluble proteins, peptides, and oligonucleotides/DNA. For delicate proteins consider using water-soluble sulfo-Cyanine 3 NHS ester which does not require use of any co-solvent. Cyanine 3 NHS ester is a replacement for NHS esters of Cy3® and DyLight 549.
