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.

Cy7 NHS ester

Amine reactive Cyanine7, near infrared fluorescent dye, an improved analog of Cy7®.

NIR fluorophores can be used to take advantage of near infrared window of biological tissues - increased transparency of tissues in this spectral region allows to carry out in vivo imaging.

This reagent can be utilized to produce Cyanine7-labeled biomolecules for subsequent use in various in vivo research, and drug design related experiments.

Appearance: green powder

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

Fluorescence quantum yield: 0.3
