A sulfonated near-infrared dye alkyne for copper-catalyzed cycloaddition with azides.

Water-soluble NIR fluorescent dye azide for click chemistry.

Biotin conjugate of the far-red fluorescent sulfo-Cyanine5 dye.

sulfo-Cyanine7.5 is a very hydrophilic and water-soluble dye for the near-infrared region. The absorption and emission spectra of the dye are similar to Indocyanine Green (ICG), but sulfo-Cyanine7.5 has a much higher fluorescence quantum yield. The dye is a great choice for near-infrared in vivo imaging. This is an azide for click chemistry.

sulfo-Cyanine7.5 is a highly hydrophilic near infrared dye for in vivo imaging. This maleimide derivative is useful for the labeling of thiol groups of proteins and peptides.

NIR dye amine, sulfonated derivative of Cyanine7 dye, for the modification via enzymatical transamination.

sulfo-Cyanine7.5 is a near-infrared fluorophore similar to Indocyanine Green (ICG) but possesses higher fluorescence quantum yield. This is an alkyne for copper-catalyzed click chemistry.

Non-functionalized NIR fluorescent dye. Water soluble heptamethine cyanine can be used as a tracing material.

A water-soluble near-infrared emitting dye for in vivo imaging applications. sulfo-Cyanine7.5 is an analog of indocyanine green (ICG) possessing higher emission quantum yield and a linker arm.

Water soluble Cyanine dye tetrazine derivative for TCO ligation with trans-cyclooctenes and other strained olefines.
