Water soluble, amino-reactive sulfo-Cyanine3 NHS ester. Efficiently labels proteins and peptides in purely aqueous solution, without need for organic co-solvent. Ideal for proteins with low solubility, and proteins prone to denaturation.
This is sulfonated, hydrophilic and water-soluble dye. Non-sulfonated Cyanine3 NHS ester is also available.
This product is an analog of Cy3® NHS ester. Sulfo-Cyanine3 NHS ester replaces Cy3® and DyLight 549 for all applications.
水溶性、氨基反应性磺基花青3 NHS 酯。 有效标记纯水溶液中的蛋白质和肽，无需有机助溶剂。 适用于溶解度低的蛋白质和易于变性的蛋白质。
这是磺化、亲水和水溶性染料。 也可提供非磺化的 Cyanine3 NHS 酯。
该产品是 Cy3® NHS 酯的类似物。 Sulfo-Cyanine3 NHS 酯可替代 Cy3® 和 DyLight 549 用于所有应用。
