Sulfo-Cyanine5 NHS ester Usage And Synthesis

Description

Water-soluble Cyanine5 succinimidyl ester (SE), an equivalent of Cy5^® NHS ester, for the labeling of various amine-containing molecules in aqueous phase without use of any organic co-solvent. This product is, therefore, particularly useful for the labeling of proteins that denature in the presence of organic co-solvents, as well as for proteins with low solubility.

sulfo-Cyanine 5 is an analog of Cy5^®, one of the most popular fluorophores, which is compatible with various equipment such as plate readers, microscopes, and imagers.

This dye is highly hydrophilic and water-soluble. A non-sulfonated analog is also available.

Can be used as a replacement for Cy5^®, DyLight 649 for all applications.
