Cy3 NHS ester is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides.

Cy3 NHS ester can replace NHS esters of Alexa Fluor 546, and DyLight 549.

This dye requires use of organic co-solvent (such as DMF, or DMSO) for the labeling. Water-soluble Cy3 is also available.

Molecular weight: 682.29

Molecular formula: C41H48ClN3O4

Solubility: soluble in organic solvents (DMSO, DMF, dichloromethane), low solubility in water

Quality control: NMR 1H, HPLC-MS (95%)

Storage conditions: Storage: 12 months after receival at -20°C in the dark. Transportation: at room temperature for up to 3 weeks. Avoid prolonged exposure to light. Desiccate.

Excitation maximum, nm: 750

ε, L⋅mol−1⋅cm−1: 199000

Emission maximum, nm: 773
