| Hazard Information | Back Directory | [Description]
Water soluble, amino-reactive sulfo-Cyanine3 NHS ester that efficiently labels proteins and peptides in purely aqueous solution without needing organic co-solvent. Ideal for proteins with low solubility and proteins prone to denaturation.
This is the 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. | [Uses]
Fluorescent dyes are typically used for imaging applications. Cy3 NHS Ester is a fluorescent dye suitable for labeling proteins and nucleic acids. It exhibits excitation and emission at 555 nm and 570 nm, respectively. Cy3 NHS Ester can be used to label functional nucleic acids to detect tertiary structure folding such as guanine quadruplex. | [Chemical Reactivity]
