Sulfo-Cyanine3 maleimide Usage And Synthesis

Description

sulfo-Cyanine3 maleimide is a water-soluble, thiol-reactive dye for labeling. This is an analog of Cy3® maleimide.

This product is recommended for labeling antibodies and other labile proteins in mild, purely aqueous conditions. The dye is water soluble and does not require organic co-solvent.

A non-sulfonated Cyanine3 maleimide is available.
