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.
非活化羧酸，Cy5® 游离羧酸的类似物。 含有Cyanine5荧光团。
这种染料的水溶性有限，但可以溶解在水与有机相（DMF、DMSO、醇）的混合物中，从而在溶液中获得有用浓度的材料。 提供水溶性版本。
这种分子可以被认为是非反应性染料，用于对照样品和仪器校准。 要与胺和蛋白质标记偶联，请考虑使用 Cyanine5 NHS 酯或水溶性磺基-Cyanine5 NHS 酯。
