Sulfo-Cyanine5 carboxylic acid
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 (***, DMSO, alcohols) to obtain useful concentrati*** of the material in solution. Water-soluble version is ***ailable.This molecule can be c***idered non-reactive dye for the use in control samples, and for instrument calibration. For coupling with amines and protein labeling, c***ider using Cyanine5 NHS ester, or water-soluble sulfo-Cyanine5 NHS ester.

Cyanine5 maleimide
Cyanine5 maleimide是单一活性染料，有选择性的与硫醇基团（比如蛋白和多肽的半胱氨酸）结合以进行标记。我们推荐使用水溶的Sulfo-Cyanine5 maleimide标记***和其他敏感蛋白。Cyanine5是Cy5®的类似物，与很多仪器比如显微镜、成像仪、荧光读板机相兼容的常用荧光团。
