Fluorescent Dyes and Probes

Fluorescent dyes and probes are molecules that emit light upon excitation by a specific wavelength, enabling visualization and quantification of biomolecules (e.g., proteins, nucleic acids, cells) in biological samples. They are foundational for fluorescence imaging, diagnostics, and high-throughput screening in life sciences. Near-infrared (NIR) dyes like ICG, Cy5.5, and Cy7 are ideal for in vivo imaging due to deep tissue penetration, while visible dyes like rhodamine are widely used in microscopy and assays.

PurePEG provides a range of Fluorescent dyes and probes, including Cy series and Rhodamine derivatives, optimized for brightness, photostability, and compatibility with biological systems.
