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.

Sulfo-Cyanine7.5 alkyne
Sulfo-Cyanine7.5 is a near infrared fluorophore similar to indocyanine green (ICG), but possessing higher fluorescence quantum yield. The dye is very hydrophilic and water soluble. The reagent is very useful for the labeling of biomolecules for in vivo imaging. This is an alkyne for copper catalyzed Click chemistry.Azidobutyric acid NHS ester
