## Descriere

Non-activated carboxylic acid, an analog of Cy5® free carboxylic acid. Contains Cyanine 5 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. A 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 Cyanine 5 NHS ester, or water-soluble sulfo-Cyanine 5 NHS ester.
