Cyanine 3 NHS ester [equivalent to Cy3(R) NHS ester]

Cyanine3 NHS ester is a reactive dye designed for labeling amino groups in biomolecules and serves as an analog of Cy3(R) NHS ester. It is particularly well-suited for labeling soluble proteins, peptides, and oligonucleotides/DNA. For more sensitive proteins, the water-soluble sulfo-Cyanine3 NHS ester is recommended, as it eliminates the need for co-solvents. Cyanine3 NHS ester is an effective alternative to NHS esters of Cy3(R) and DyLight 549. Chemical Properties Storage Upon receipt, store at -20°C in the dark. Protect from light and moisture.
