Lumiprobe 磺酸基CY 3马来酰亚胺 Sulfo-Cyanine3 maleimide
Sulfo-Cyanine3 maleimide is a water soluble, thiol reactive dye for the labeling with hydrophilic sulfo-Cyanine3 fluorophore. This is an analog of Cy3® maleimide.
This product is recommended for the labeling of antibodies and other labile proteins in mild, purely aqueous conditions. The dye is water soluble and does not require use of organic co-solvent.
