Sulfo-Cy5 carboxylic acid，1121756-16-8
非活化的sulfo-Cyanine5羧酸，水溶性染料。该染料高度亲水和水溶。非磺化的类似物。
该荧光团是Cy5®羧酸的同等类似物。
对于标记反应请考虑使用活性染料sulfo-Cy5 NHS ester。
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.
