Sulfo-Cy7 maleimide is water soluble cyanine dye containing a maleimide group which is commonly reacted with thiols to form a thioester bond at pH 6.5 to 7.5. This NIR dye amine can be used to derivate various targets by the reaction with electrophilic groups, and by enzymatical reactions involving transamination. | [Uses]
Sulfo-Cyanine7 maleimide potassium is an analogue of Cy7 maleimide and a hydrophilic near-infrared fluorescent dye. | [References]
