Sulfo Cy7 Maleimide Usage And Synthesis
DescriptionSulfo-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.
UsesSulfo-Cyanine7 maleimide potassium is an analogue of Cy7 maleimide and a hydrophilic near-infrared fluorescent dye.
