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.
