Amine reactive Cyanine7, near infrared fluorescent dye, an improved analog of Cy7®.
NIR fluorophores can be used to take advantage of near infrared window of biological tissues - increased transparency of tissues in this spectral region allows to carry out in vivo imaging.
This reagent can be utilized to produce Cyanine7-labeled biomolecules for subsequent use in various in vivo research, and drug design related experiments.
The structure of Cyanine7 features rigidized design of central polymethyne chain. This molecular reinforcement allows to increase quantum yield by 20% compared with parent structure, increasing fluorescence brightness.
This reagent requires organic co-solvent for the labeling (please see Recommended Protocols section below). Water-soluble Cyanine7 NHS ester is also available, and recommended for protein NIR labeling.

THPTA ligand
THPTA is a water soluble ligand for Cu(I) catalyzed Click chemistry. The ligand stabilizes copper in its Cu(I) oxidation state. Due to high aqueous solubility, reactions with this ligand do not require an organic co-solvent.Cyanine3 amine
Cyanine3 is an fluorophore with free amino group (amino-dye). It can be conjugated with NHS esters, carboxy groups (after activation), and epoxides.Cyanine5 alkyne
Cyanine5 alkyne is an alkyne dye for Click Chemistry.General properties
