DyLight 550 NHS ester

Catalog No.: A45524
Fluorescent Dye
DyLight 550 NHS ester is a fluorescent dye designed for advanced labeling applications in biochemical research. This vibrant orange-to-red fluorochrome exhibits superior performance compared to traditional rhodamine derivatives, facilitating enhanced detection and analysis. Its high water solubility allows for an optimal dye-to-protein ratio, ensuring efficient conjugation without precipitation of the labeled conjugates. DyLight 550 is ideal for applications such as immunofluorescence, flow cytometry, and live cell imaging.
