Free Cyanine3 carboxylic acid (Cy3® carboxylic acid analog), non-activated dye. Non-sulfonated reagent, with good solubility in organic solvents, and limited aquous solubility. The dye can be used as a non-reactive fluorophore, for control experiments, and for calibration.
For coupling with amines, and labeling, consider using Cyanine3 NHS ester, or water-soluble sulfo-Cyanine3 NHS ester.
游离Cyanine3 羧酸（Cy3® 羧酸类似物），非活化染料。 非磺化试剂，在有机溶剂中溶解性好，水溶性有限。 该染料可用作非反应性荧光团，用于对照实验和校准。
对于与胺偶联和标记，请考虑使用 Cyanine3 NHS 酯或水溶性磺基-Cyanine3 NHS 酯。
