Sulfo-Cyanine5 dUTP (deoxyuridine triphosphate) is a modified nucleoside triphosphate for the enzymatic labeling of DNA. The triphosphate is an analog of Cy5-dUTP. However, unlike aminoallyl dUTP directly modified with dye, this triphosphate contains a longer linker arm that increases the efficiency of its incorporation by usual polymerases, like Taq polymerase.

Sulfo-Cyanine5 is a bright far red emitting dye for Cy5 channel.

The triphosphate is supplied in lyophilized form of lithium salt, ready to use.
