Sulfo-Cyanine5 maleimide Usage And Synthesis

Uses

The water-soluble anthocyanin dye CY5 maleimide is a fluorescent dye that can be used to label biomolecules for fluorescence imaging and other fluorescence-based biochemical analyses.

Description

A water soluble, hydrophilic sulfo-Cyanine5 maleimide (Cy5® maleimide analog). We recommend this product for protein labeling, including labeling of antibodies as a perfect replacement for Cy5® maleimide. Labeled proteins can be easily separated from unreacted dye by gel filtration, spin column purification, dialysis, electrophoresis or chromatography.

An analog without sulfo groups, Cyanine5 maleimide, is also available.
