Non-activated carboxylic acid, an analog of Cy5® free carboxylic acid. Contains Cyanine5 fluorophore.
This dye has limited water solubility, but can be dissolved in mixtures of water with organic phase (DMF, DMSO, alcohols) to obtain useful concentrations of the material in solution. Water-soluble version is available.
This molecule can be considered non-reactive dye for the use in control samples, and for instrument calibration. For coupling with amines and protein labeling, consider using Cyanine5 NHS ester, or water-soluble sulfo-Cyanine5 NHS ester.

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.Sulfo-Cyanine7 carboxylic acid
Sulfo-Cy7 carboxylic acid is a non-reactive fluorescent dye which can be used as a NIR (near infrared) marker.Sulfo-Cyanine5 carboxylic acid
Water-soluble Cyanine5 carboxylic acid, non-activated fluorescent dye.General properties
