Cy5 NHS ester is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides.

Cy5 NHS ester can replace NHS esters of Alexa Fluor 647, DyLight 649.

This dye requires organic co-solvent (such as DMF, or DMSO) be used in labeling reaction. Water-soluble Cy5 NHS ester is also available.

Molar weight: 616.19

Mass spec M+ increase: 465.6

Cy5 excitation maximum, λmaxex, nm: 646

Cy5 extinction at λmaxex 250,000

Cy5 emission maximum, λmaxfluor, nm: 662

Cy5 fluorescence quantum yield: 0.2

NMR: 95+%

TLC: pure

Functional testing (reaction with amine): pass

Store NHS esters at -20°C in the dark. Desiccate.
