非活化的sulfo-Cyanine5羧酸，水溶性染料。該染料高度親水和水溶。非磺化的類似物。該熒光團是Cy5®羧酸的同等類似物。對于標(biāo)記反應(yīng)請考慮使用活性染料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.
