Flourescent PEG

Flourescent PEG

Synonyms: FITC PEG

Flourescent PEG is a PEG derivative whose molecular chains contain fluorescein. Fluorescein often called FITC is a commonly used fluorescent tracer in biology for staining cells, tissues, biomarkers or nanoparticles. It has peak absorption or excitation at 494 nm and maximum emission at 521 nm. Fluorescent PEG is commonly used for PEGylation to label or tag biomolecules and nanoparticles with dye and tracer. Compared with conventional fluorescent molecules, the PEGylated fluorescent probe has superior performance due to its improved hydrophilicity. These fluorescent probes (Cy3, Cy5, Cy7, BDP, Rhodamine, Pyrene,…) emit light from the UV to the near-infrared region. They can be used to label proteins, antibodies, peptides, nucleotides, particles and many other materials.
