Product Description

Cyanine dye with an aminooxy reactive group can be used to fluorescently label target molecules with an aldehyde or ketone group. Aminooxy group readily reacts with an aldehyde or ketone group to form a stable oxime linkage without the use of reducing agents. We offer Cyanine 647 Aminooxy and Cyanine 555 Aminooxy.
