Lumiprobe 水溶性CY3 NHS酯 Sulfo-Cyanine3 NHS ester
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®, Alexa Fluor 546, and DyLight 549 for all applications.
